As we study God’s Word and allow it to train our conscience, we find two opposite actions take place simultaneously. We discover that we add restrictions to our conscience. We find that certain beliefs or actions we did not take seriously are, in fact, to be taken seriously. At the same time, we discover that we remove restrictions from our conscience. We learn that some specific actions are not sinful but were engrained into us through tradition or held due to a misunderstanding of God and His Word. Last week we examined what it looks like when we allow God’s Word to train our conscience that some things we previously thought were sin are not sin.

On the other hand, training our conscience also involves adding to our conscience. Sometimes, our conscience should bother us regarding sin, but it fails to do so as we have seared it. It is necessary in these cases to allow Scripture to inform us that our views need to change. We must conform our conscience to God’s Word by refraining from these actions.

Corinth was known in the ancient world for its sinful atmosphere. As a result, the Corinthian church often had to adjust their conscience so that their conscience would convict them of sin. In 1 Corinthians 5, Paul takes the church to task for such an incident. Apparently, a church member became engaged in gross, incestuous immorality. Instead of addressing the issues, the church celebrated the fact that this was taking place. The individual did not view his action as a sin. The church members took pride in including this individual. Rather than mourn over sin, they rejoiced over sin. Their conscience was so misinformed and seared it allowed this evil. Paul instructed the church to purge the evil from their midst and to seek righteousness.

Unfortunately, these kinds of instances happen often in the church today. Rather than confine sex to marriage, churches celebrate when couples move in with one another. We allow our feelings and excitement to inform our conscience rather than God’s Word. Instead, we should instruct our conscience with texts like Hebrews 13:4 and seek purity. Only when we fill ourselves with God’s Word can we stand with a clear conscience against the world’s corruption.

As our world becomes more politically divided, we find ourselves falling back into the pattern seen in the Roman Empire. While we indeed should obey God over man, and there are times to resist our government leaders when they violate clear Scripture, we must always seek to honor our government leaders. Yet, honoring bad civil leadership goes against our natural tendencies. We must train our conscience with texts like 1 Peter 2:17 so that our conscience will sound the alarm when we are tempted to engage in conversations and actions that denigrate our civil leaders. As we come to understand God’s Word better, we will arrive at more opportunities to add rules to our conscience and weed out bad rules from our conscience because we will come to a greater understanding of what pleases God.

To use the God-given alarm system of the conscience, we should teach our conscience what those good, right, and true things are. The word discern in Ephesians 5:10 refers to the idea of putting to the test. We should constantly evaluate the situations, thoughts, beliefs, and convictions we come in contact with to understand what pleases God. This testing must have a standard against which we examine all we come into contact. Unfortunately, we often measure our experiences and beliefs according to our feelings. As a result, our conscience responds either by excusing our actions or making dark accusations against us. “Error, human wisdom, and wrong moral influences filling the mind will corrupt or cripple the conscience.”[1]

How, then, should the Christians train their consciences? The writer of Hebrews informs us through one of the most glorious passages of Scripture. In Hebrews 10, the writer demonstrates that Christ has perfectly fulfilled the Law for us. He is the great and better High Priest who has procured our atonement by sacrificing His perfect blood. For millennia, God required sacrifice to atone for man’s guilt. However, these sacrifices did not atone for man’s sin. Instead, they pointed to the perfect atonement that would come through the sacrifice of the Sinless Christ.

Because we no longer stand in condemnation before God (Romans 8:1), we can now confidently enter God’s holy throne room through prayer. As we enter with confidence, the writer of Hebrews challenges us to come with consciences sprinkled clean and washed with pure water. Christians seek to find what pleases God to approach God with a clean conscience. Verses 26-31 reveal that we strive to refrain from sin. While verses 32-39 reveal that we do this by understanding our faith and the sacrifice of Christ.

The author of Hebrews is building off the concept that Paul presented to the Ephesian church in Ephesians 5. As Paul presents a picture of a biblical marriage relationship for the church, he reminds them that marriage is to be a picture of the Gospel. In verse 26, Paul reveals that God has redeemed His church (us) and will present us blameless before God by washing us with the water of the Word. So, we can see that the primary way we train our conscience is through God’s Word. We understand what pleases God by understanding God through His Word. This means that we must constantly study God’s Word. And, as we study, we must do so, not just to re-enforce what we already think, but to challenge, refine, and change what we believe.

Pastors often teach their congregations to allow God’s Word to adjust their framework. We all have a framework by which we think and act. Our default position is to force our framework onto Scripture and use Scripture to bolster our ideas. If we come across a text that challenges our framework, we ignore it. Yet, when we do this, it has tragic results on our conscience. Our consciences remain uncalibrated and give us wrong results. So, we must read Scripture with humility so that it can change our thinking.

Since violating and ignoring our conscience is a sin, it is vital that we train our conscience to rightly warn us of sin. A conscience that fails to warn us of sin is like a smoke detector without batteries. It is hanging on the ceiling, but it is of no use. When the fire starts, we will have no warning. One the other hand, a conscience that warns us of things that are not sin binds us to a legalistic and bitter lifestyle apart from the freedom the Gospel provides. Therefore, training our conscience becomes necessary to a vibrant Christian life.

Each summer my lawn begins to grow. In Michigan, spring often arrives suddenly. Because of the wet environment, the grass grows and mowing becomes a weekly (and sometimes daily activity). As the summer progresses, I need to continually care for my lawn mower. Each week I need to fill it with gas, check the oil level and quality, and maintain the blades sharpness. If I fail to keep an eye on these things, my lawn begins to suffer. In a similar way, our conscience requires consistent maintenance and training.

In Ephesians, Paul informs us that we should train our conscience to understand what pleases the Lord. “For at one time you were darkness, but now you are light in the Lord. Walk as children of light 9 (for the fruit of light is found in all that is good and right and true), 10 and try to discern what is pleasing to the Lord” (Ephesians 5:8-10). While we once walked in sin and did not care if we pleased God, this is no longer the case. Now we care deeply about what pleases God.

No longer should Christians live like they did as unbelievers. We are children of the light and we must live like it. This involves those things that are good, right, and true. Immediately, one should think of the fruit of the Spirit in Galatians 5. Our lives are no longer marked by the works of the flesh. The character and pattern of our life should immediately reveal that something different has taken place within us.

In order to use the God given alarm system of the conscience, we should teach our conscience what those good, right, and true things are. Paul informs us that this involves discernment. The word translated discernment holds the idea of testing and examining. A right conscience does not come by accident. Instead, Christians are to intentionally take steps to ensure that their conscience understands what pleases God.

With any discussion surrounding the conscience, we must remember that it has been impacted by the fall. If we fail to understand this critical point, we can fall into serious danger through our conscience. Scripture reveals that the conscience can be seared, scarred, and ignored. When we ignore and violate our conscience, it is a sin and has real-world consequences.

As we ignore our conscience, Scripture reveals that it becomes seared (1 Timothy 4:2). As we ignore our conscience’s warning, we stop feeling its pangs. In high school, several of my friends and I worked in jobs involving mowing and landscaping. When we started these jobs, we developed blisters on our fingers and palms from our tools. Over time, these blisters hardened into deep patches of dead skin or callouses. The thing about callouses is that you cannot feel anything through them. We would often disgust the girls we knew by taking pins and running them through the callouses. We were able to do so because they were unfeeling. The skin was dead and desensitized, so we received no warnings of pain. This is the illustration that Paul uses for the conscience that no longer warns of impending sin and error. It has been so ignored we can no longer feel it.

In 1 Timothy 4, Paul warns Timothy and the church of impending danger, not from outside the church, but from inside the church. Some who claim to be Christians would move away from God’s Word and lead others with them. They would depart because they would buy into false teaching subtly brought into the church by Satan. While they initially felt the pangs of conscience, they ignored these warnings. They seared their conscience by convincing themselves that their actions were right.

Some who are part of the body of Christ, some who seem to be Christians, will depart from the Word and will begin to make Christianity something that it is not. They will turn away from the theology of the Word and begin to accept and promote the humanism of the world. An important lesson is that a mere profession of faith does not guarantee the actual possession of eternal life. Just because something or someone claims to be Christian does not make it so. We are reminded of the parable of the seeds. Some seeds will appear to take root but are not genuine.

The cause of their departure is not their high intellect. The cause of their departure is not some new revelation. The cause of their departure is not an overwhelming love for people, which drives a desire to make Christianity palatable. No! Paul informs us that the cause of their departure is something far more sinister. It is the false teaching from Satan that makes that which is wrong seem like it is right. Another important note is that these errors rarely come through people easily identified as non-Christians. They are nice people. They don’t seem to be doing wrong. But this is because they have had their conscience seared. These people have no sense of the heinousness of their actions because their consciences have been seared as with a hot iron. By constantly arguing with conscience, stifling its warnings, and silencing its alarm, these people have reached the point where their conscience no longer bothers them. “Grieving the Holy Spirit has led to resisting him, and resisting him to quenching him. Then, through their own rebellion and obstinacy, their conscience will have been rendered (and that will be permanently) seared.”[1]

When we no longer listen to our conscience, it becomes quieter until it is imperceptible. Don Carson notes that this silence becomes incredibly dangerous because we get into the habit of ignoring the conscience even when it is appropriately warning us of evil.[2] Through this repeated abuse, we nullify the conscience and make it worthless. Suppose we persist in setting our minds on earthly things. In that case, we can arrive at the point where we boast about things we should be ashamed of (Philippians 3:19). As we continually defy our conscience, we can no longer distinguish between right and wrong. Sadly, when these warnings fall silent, the danger is not gone. We are in a more perilous position.[3]

As society slides further into ruin, Christians stand in danger of joining in this slide when we ignore our conscience. The writer of Hebrews informs us that our conscience is deceived by sin and, through this deceit, is hardened (Hebrews 3:13). Unfortunately, this hardened conscience falls into pride and becomes further desensitized to sin. This process leads to a vicious cycle through which sin desensitizes our conscience, and our desensitized conscience leads to more sin. Romans 1 indicates that as society slides deeper into this cycle, God judges the culture by removing his presence and allowing sin to be its just result.

Ignoring the conscience becomes one of the most dangerous actions a Christian can take. Through this action, the Holy Spirit’s tool in our lives to warn us of sin falls silent. We begin a slide into deeper sin without shame because we sear our conscience. As we make decisions, then, it becomes vital that we listen to our conscience. While others may think we are soft or foolish, listening to your conscience is a sign of wisdom.

As we seek to make biblical decisions, the conscience should play an essential role. We discussed the decisions we should make on debatable issues when others disagree with our choices. However, what should we do when we disagree with our decisions? This seems like a weird question. However, many people seek to suppress their guilt and feelings of anxiety and move forward with their choices, giving no thought to their conscience. Others view their conscience as though it is never wrong and end up binding themselves unnecessarily. Individuals arrive at both bad ends because they fail to understand their conscience. The conscience may be the most underappreciated and misunderstood part of the human being. Modern psychology seeks not to understand the conscience but to silence it. Rather than address the guilt from the conscience, they seek to silence the conscience through affirmation. Unfortunately, this same attitude has infiltrated the modern church as well. Many Christians seek ministers and counselors who will tickle their ears rather than address their hearts.[1]

To combat this mistreatment of the conscience, we must understand our conscience. Scripture has much to say about the conscience. In the New Testament, the word translators have translated as conscience appears thirty times. Examining these texts, we conclude that the conscience is God’s gift to man to help us towards moral purity. Some define the conscience as “your consciousness of what you believe is right and wrong.”[2] However, Romans 2 indicates that our conscience is much more. It is the God-given alarm system that alerts us to our violation of God’s Law. The Puritan Richard Sibbes defines the conscience as the soul reflecting upon itself.[3] Yet, because our conscience is part of us, it is also impacted by the Fall. As a result, it is also affected by what we believe to be right and wrong.

Therefore, the conscience is both a tremendous asset and a dangerous ally. As J. I. Packer notes, “An educated, sensitive conscience is God’s monitor. It alerts us to the moral quality of what we do or plan to do, forbids lawlessness and irresponsibility, and makes us feel guilt, shame, and fear of the future retribution that it tells us we deserve, when we have allowed ourselves to defy its restraints.”[4] In the right place, the conscience is a wonderful asset for Christlike sanctification and a necessary protection against sin.

Yet our conscience is also subject to the Fall and, therefore, not inerrant. Satan seeks to use our conscience against us. He corrupts and desensitizes our conscience so that it will not alert us to evil. Satan uses the worldly attitudes and beliefs surrounding us to dull our conscience to sin. As we consistently encounter sin, we fail to take notice. When we do notice, our conscience brings guilt, shame, and unease. Sibbes compared the feelings aroused by the violated conscience to “a flash of hell.”[5] Because these feelings are painful, the world informs us that guilty feelings are always erroneous and hurtful. Just ignore them.

As we ignore the conscience’s feelings, we begin to fail to notice any presence of our conscience. I grew up just a few blocks from Buckley Air Force Base in Aurora, Colorado. Every day, a squadron of F-16s would take off and fly around the city. Visitors consistently noticed and commented on the aircraft noise. Bizarrely, those of us who lived there never noticed the noise. Our minds had filtered it out so much that we rarely noticed it. When visitors noticed, we acknowledged what they heard and informed them that they would no longer notice in a short while. In the same way, Satan uses constant confrontation with sin in our lives and culture to dull our conscience to its presence and effects.

When Satan cannot dull our conscience, he heightens our conscience so that it falsely accuses us and unnecessarily binds us. He cripples us with guilt over things that are not sin. He causes us to call things sin, which are not sin, and undermine the gospel in our lives. Rather than enjoying the freedom God grants through the gospel, we become bitter and resentful as we seek to please God through our self-righteousness. Both cases (the dull and the heightened conscience) reveal that while it is a gift of God, the conscience is not inerrant. So, we cannot always heed Jiminy Cricket’s advice to let our conscience be our guide. Yet, neither can we afford to ignore it.

As Christians examine the Old Testament, they strangely discover a seeming absence of any reference to the conscience. However, this absence is not because the conscience is a New Testament invention. Instead, the conscience is so much a part of us that the Hebrew mind did not distinguish between the conscience and the individual. They viewed the inner person and the conscience as inseparable.[6] A well-known example of this blending of the conscience with the inner person can be examined in Exodus. When God, through Moses, commanded Pharaoh to let the Israelites go, Moses informs us that Pharaoh “hardened his heart” (Exod. 8:15). Pharaoh ignored his conscience (his heart) and turned off the God-given alarm system.

Blending the inner person with the conscience is important because it informs us that we cannot ignore the conscience (for it is an essential God-given asset). Nor, as fallen creatures with an innate sinful nature, can we afford to assign an all-knowing nature to the conscience (doing so would make it a dangerous ally). Instead, we must seek to hold our conscience in its rightful, God-given place and treat it in a way that it can accomplish its rightful, God-given purpose. Next week, we will address how we can hold the conscience in its rightful, God-given place. To do this, we must understand how our conscience is corrupted and redeemed.

Today we celebrate Christ’s death. Two thousand years ago, on that fateful day, Christ suffered and died for our sins. As you meditate on Christ’s death today, here is a rough schedule of that day Christ purchased our redemption:

4:00-6:00 am – Jesus was brought before Caiaphas and Annas for trial. They could not find anything to convict Jesus, so a false witness was brought. Asked if He is the Christ, Jesus responded, “You have said it yourself.” He was then beaten and spit on.

As Jesus stood before Caiaphas and Annas, Peter made his way to the courtyard outside. Confronted about being one of the Jesus People, he flatly denied it. By the third confrontation, he began to curse. Then the rooster crowed; Peter saw Jesus leaving the compound and wept in shame.

6:00-8:00 am – Daylight appeared, and the Jewish leaders dragged Jesus to Pilate for sentencing. However, Pilate had no desire to become involved in what he perceived to be a no-win situation. He stated, “I find no guilt in this man.” Asking if Jesus is Galilean, Pilate found a jurisdiction loophole. So, he sent Jesus to Herod, who oversaw Galilee.

Herod attempted to question Jesus, but Jesus kept silent. Finally, Herod allowed his soldiers to abuse Jesus and sent Him back to Pilate.

When Jesus arrived back before Pilate, Pilate continued to question Jesus. However, Jesus continued to remain silent. Marveling at Jesus’ composure, Pilate offered the gathering crowd the opportunity to release Jesus. However, with the urging of the religious leaders, the crowd demanded that Pilate release a thief and murderer named Barabbas instead. They then demanded that Pilate crucify Jesus. After symbolically washing his hands, Pilate turned Jesus over for death.

After Jesus was condemned, the soldier renewed their abuse. They whipped Him, beat Him, jammed a crown of thorns on His head, and put a purple robe on His bloody and tattered body. After humiliating Jesus, they removed the robe and prepared a bloody and battered Jesus for death.

8:00-8:30 am – Jesus began the trek through the city and outside the walls to Golgotha for crucifixion. Having endured so much abuse, He could not carry His cross. The soldiers grabbed a man named Simon from the crowd and forced him to take Jesus’ cross the rest of the way.

As Jesus made his way to Golgotha, a crowd followed him weeping. Jesus turned and told them not to weep for Him but for themselves. For, if the leaders did this when Jesus was with them, what would they do when He was gone?

9:00 am – The group arrived at Golgotha. They stretched Jesus’ arms across the beam and nailed his wrists to the wood. They then nailed his ankles to the vertical piece and hoisted the cross in place. The process of procuring our redemption had begun.

9:00-9:30 am – Jesus was offered a drink to numb the pain, but He refused. Having completed their work, the soldiers settled in for a day of watching the criminals die. They began to cast lots to determine who got to take home the various items of the criminal’s clothing.

The soldiers placed a placard over Jesus stating His “crime”: He was the King of the Jews. He cries out, “Father, forgive them. For they know not what they do!”

9:30-11:00 am – The Chief Priests, Scribes, and soldiers begin to abuse Jesus verbally. “He saved others; He cannot save Himself.” “He is the King of Israel, let Him come down from the cross, and we will believe.” Of course, they wouldn’t believe it. Jesus had done various miracles, but they only cared for their power. “He trusts in God; let God rescue Him. He claims to be the Son of God.” The two thieves began to get in on the verbal abuse through the pain. “Are you not the Christ? Save yourself and us!”

11:00 am -12:00 pm – One of the thieves fell under conviction and rebuked the other thief. He then turned to Jesus and asked to be remembered when Christ came to His Kingdom. Jesus responded with forgiveness, “Today you will be with Me in paradise!”

Through the pain, Jesus looked down and observed a group of women, His mother, and John. He instructed John to care for Mary. And from that day forward, John took her into his house. Even in death, Jesus continued to show compassion.

12:00-3:00 pm – An eerie three-hour darkness fell across the land. The sun would not shine on the death of its Creator. After hanging on the cross all morning, Jesus’ body began to dehydrate from the loss of fluids, and his lungs screamed out for oxygen. Pushing up against the nails, He struggled for a breath. But the dehydration would cause his muscles to cramp, and he would drop back down and begin to suffocate.

The darkness continued, and our sin was placed on Jesus. The Father turned His face away from His Son for the first time. Jesus cried out, “My Father, My Father, why have You forsaken Me?” He was made sin for us!

Suffering from intense dehydration and suffocation and knowing that only one Scripture remained which He needed to fulfill, Jesus cried out, “I thirst!” Someone brought a sponge dipped in sour wine.

Redemption had been paid. Jesus cried out, “It is finished!” Paid in full! He paid a debt he did not owe and placed righteousness on the accounts of the elect. Jesus then cried out again with a loud voice, “Father, into Your hands I commit My spirit!” And the Savior died. Earth raged. A great earthquake struck, rocks split, the veil in the Temple ripped, and tombs opened. The Centurion stated in awe, “He was the Son of God!”

He himself bore our sins in his body on the tree, that we might die to sin and live to righteousness. By his wounds you have been healed. (1 Peter 2:24)

Surely he has borne our griefs and carried our sorrows;
yet we esteemed him stricken smitten by God, and afflicted.
But he was pierced for our transgressions; he was crushed for our iniquities;
upon him was the chastisement that brought us peace, and with his wounds we are healed.
All we like sheep have gone astray; we have turned—every one—to his own way;
and the Lord has laid on him the iniquity of us all. (Isaiah 53:4-6)
