Convicted by Conscience

The Voice Inside

☐

When Jesus said, “He who is without sin among you, let him throw a stone at her first,” something happened inside every accuser. John says they were “convicted by their conscience” (John 8:9). What is a conscience, and what should we do when it speaks?

A warning light. Your conscience is the sense God put inside you that tells you when something is right or wrong. It works like a warning light on a car. When it comes on, it is telling you to stop and look.

A kind gift. A conscience is a gift from God, not a punishment. When you touch a hot stove, the pain makes you pull your hand away before it is badly burned. A guilty feeling warns you to stop before sin hurts you and others more.

God made it. The Bible teaches that God has written what His law requires on people's hearts. Even people who have never read the Bible know that some things are wrong, and their thoughts accuse them when they do wrong (Romans 2:15).

The first hiding. After Adam and Eve disobeyed God, “Adam and his wife hid themselves from the presence of the Lord God among the trees of the garden” (Genesis 3:8). Adam said, “I heard Your voice in the garden, and I was afraid” (Genesis 3:10). A guilty conscience makes people want to hide.

A governor who was afraid. When Paul spoke to Governor Felix about righteousness, self-control and the judgment to come, Felix was afraid, but he sent Paul away for another time (Acts 24:25). His conscience spoke, and he put it off.

David's heart. When David secretly cut off a corner of King Saul's robe, “David's heart troubled him” (1 Samuel 24:5). Years later, after he counted the people, “David's heart condemned him” (2 Samuel 24:10). Both times David listened and turned back to God.

The men in the temple. The accusers listened to their conscience enough to stop and leave. But they walked away from Jesus instead of coming to Him.

Training your conscience. A conscience works best when it is filled with God's Word. “Your word I have hidden in my heart, That I might not sin against You” (Psalm 119:11).

Do not ignore it. A conscience that is ignored again and again can grow hard, the way skin gets tough and stops feeling. Paul warned about people whose conscience had become like that (1 Timothy 4:2).

What we learn. When your conscience tells you that you have done wrong, do not hide like Adam, and do not walk away like the accusers. Come to Jesus. He is the only one who can take your guilt away.

“Then those who heard it, being convicted by their conscience, went out one by one” (John 8:9). Jesus' words reached into each accuser's heart. The Bible has much to say about that inner voice.

Syneidesis. The Greek word for conscience is syneidesis (say: soon-AY-day-sis). It means knowing together with: an inner witness that knows what you have done and speaks up about it.

Written on the heart. Paul teaches that people who never had the written law still show the work of the law written in their hearts, with their conscience bearing witness and their thoughts accusing or excusing them (Romans 2:15). The conscience is part of how God made us.

Hiding (Genesis 3:8-10). The first sin brought the first guilty conscience. Adam and Eve hid “from the presence of the Lord God,” and Adam said, “I was afraid.” Guilt pushes people away from the God who made them.

Put off for later (Acts 24:25). When Paul spoke to Governor Felix about righteousness, self-control and the judgment to come, Felix was afraid, but he sent Paul away for another time. Fear is not the same as turning to God. A conscience can be heard and still be put off.

A tender conscience (1 Samuel 24:5). David's heart troubled him over a corner of cloth. A heart that listens to God notices even small wrongs.

Before and after. A conscience can warn before we sin and accuse after we sin. In the cave it did both for David: his heart troubled him after he cut the robe, and it made him hold his men back so they did not harm Saul (1 Samuel 24:5-7).

Conviction that leads to confession (2 Samuel 24:10). When “David's heart condemned him,” he said, “I have sinned greatly in what I have done.” His conscience drove him toward God, not away from Him.

Conviction without coming. The accusers in John 8 felt the same conviction, yet they went out. A troubled conscience is meant to bring us to God, not to send us away from Him.

Shaped by the Word. A conscience can be mistaken, so it needs God's Word. “For the word of God is living and powerful… and is a discerner of the thoughts and intents of the heart” (Hebrews 4:12). Ignored for long enough, a conscience can grow hard and stop warning (1 Timothy 4:2).

Why it matters. Your conscience can tell you that you are guilty, but it cannot make you clean. It points you to the One who can.

A Clean Conscience

☐

A conscience can tell you that you are guilty. It cannot make you clean. Only Jesus can do that. So what do you do with a guilty conscience?

Cut to the heart. On the day of Pentecost, Peter told a huge crowd that they had crucified Jesus, whom God had raised. “Now when they heard this, they were cut to the heart, and said to Peter and the rest of the apostles, ‘Men and brethren, what shall we do?’” (Acts 2:37).

Two different answers. The accusers in the temple were convicted too, but they went out and left Jesus. The crowd at Pentecost asked what to do, and thousands turned to Jesus. A guilty conscience is meant to send us to God, not away from Him.

God's promise. “If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness” (1 John 1:9). God does not only forgive. He cleans.

Washed by Jesus' blood. “How much more shall the blood of Christ, who through the eternal Spirit offered Himself without spot to God, cleanse your conscience from dead works to serve the living God?” (Hebrews 9:14). Jesus died on the cross to take guilt away, not just to cover it up.

He carried it. Jesus “Himself bore our sins in His own body on the tree” (1 Peter 2:24). Then He rose again, and He is alive to forgive everyone who comes to Him.

Come close. “Let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience” (Hebrews 10:22). People who trust Jesus can come close to God without fear.

When feelings linger. Sometimes a Christian still feels guilty after God has forgiven him. John wrote that when our heart condemns us, God is greater than our heart and knows all things (1 John 3:20). Trust what God says more than what you feel.

Keeping it clean. Paul said he always tried to have a conscience without offense toward God and people (Acts 24:16). We do that by obeying God and by confessing quickly when we fail.

What we learn. A guilty conscience is not the end of the story. Do not walk away like the accusers. Tell God the truth, trust Jesus, and let Him make you clean.

Conviction drove the accusers out, but leaving could not remove their guilt. The woman, still standing there, heard, “Neither do I condemn you” (John 8:11). The New Testament shows how a guilty conscience is made clean.

Cut to the heart (Acts 2:37). At Pentecost Peter preached that Jesus, whom they had crucified, was risen and was Lord and Christ. The crowd “were cut to the heart” and asked, “Men and brethren, what shall we do?” Conviction that asks the right question leads to life.

Faithful and just (1 John 1:9). God forgives confessed sin because He is faithful to His promise and just, since Christ has already paid for it.

Katharizo (Hebrews 9:14). The word for cleanse is katharizo (say: kah-thah-REED-zoh), to make clean. The animal sacrifices of the old covenant could make a person outwardly clean, but “the blood of Christ” cleanses the conscience. “Dead works” are works that cannot give life, such as trying to earn God's favor. Jesus frees us from them.

Bore our sins (1 Peter 2:24). “Who Himself bore our sins in His own body on the tree, that we, having died to sins, might live for righteousness.” The guilt was not ignored. It was carried and paid for, and He rose again.

Draw near (Hebrews 10:22). “Having our hearts sprinkled from an evil conscience.” A cleansed conscience does not run from God; it comes to Him “in full assurance of faith.”

Greater than our heart (1 John 3:20). Feelings of guilt can linger after forgiveness. John answers that God is greater than our heart and knows all things. His verdict outweighs our feelings.

Not by feelings alone. A clean conscience does not mean we will never feel sorry again. It means we know the debt is paid, so guilt sends us back to Jesus instead of away from Him.

A conscience kept clean (Acts 24:16). Paul worked at keeping a conscience without offense toward God and people. Forgiven people listen to their conscience and keep short accounts with God.

Why it matters. Every person has a conscience that accuses. Only the cross can answer it. Jesus does not ask us to silence our conscience; He makes it clean.
