How to Get and Keep a Good Conscience

Weekly Bible E-Newsletter to Help You Open Your Bible

I strive always to keep my conscience clear before God and man. (Acts 24:16) 

Conscience gives you the ability to evaluate your own thoughts and desires, to discern what is right and wrong, and to distinguish between what is good and what is best.  

To help us get a handle on conscience and how it functions, I want you to think about an alarm clock. A good alarm clock does two things: It stays quiet when you should be asleep, and it makes a noise when you need to wake up! 

That’s how your conscience is supposed to work. When you are on the right path, a good conscience will be at peace (Colossians 3:15). But when you are tempted towards the wrong path, a good conscience will sound the alarm. The problem with the conscience is that, like every other part of your soul, it has been disordered by sin. 

Like an alarm clock, conscience can malfunction and stay silent when it should go off. 

My Alarm Didn’t Go Off! 

The corrupt conscience 

To the pure, all things are pure, but to those who are corrupted and do not believe, nothing is pure. In fact, both their minds and consciences are corrupted. (Titus 1:15) 

Acting against your conscience will bring a change in your inner life. It will change how your conscience functions. A corrupt conscience approves the wrong things. 

An easy way to see this is to picture a teenager using drugs for the first time. He knows that drugs are addictive and destructive, and his conscience tells him that taking them is wrong. But his friends are encouraging him to try them. He wants his friends to like him. So he over-rides his conscience.

In over-ruling his conscience, he diminishes its power. His conscience is weakened. It is less sensitive, and therefore less effective. Next time, the decision to take the drug will be much easier. If the boy repeats this choice again, the boy’s conscience changes. After a while he will feel that there is nothing wrong with what he is doing.  

The important point to grasp here is that the conscience is corrupted whenever a person acts against it over time. When a person’s conscience is corrupted over time, it can become seared. 

The seared conscience 

Such teachings come through hypocritical liars, whose consciences have been seared as with a hot iron. (1 Timothy 4:2) 

In the ancient world, doctors would use a hot iron to cauterize a wound. It hardly bears thinking about what this must have been like before anesthetic, but if you had a wound and the bleeding could not be stopped, your best hope was the hot iron pressed on your flesh.

Once you recovered from the pain, you would discover that the bleeding had stopped, but you would also find that you had lost all feeling in the area that had been seared. The hot iron killed off the nerves so that you no longer had feeling where the iron had been applied. 

Paul says, “That’s how it is with some people’s conscience.” They have been “seared as with a hot iron” (Ephesians 4:19). Their conscience has lost all sensitivity. When that happens, a person can lie, cheat, or steal without their conscience raising any objection. They feel no guilt because their conscience is seared. 

As he was on the road to Damascus, that’s exactly what Saul of Tarsus thought. Do you think he was worried about doing something wrong? The seared conscience calls evil “good” and good “evil” (Isaiah 5:20).  

How to Get and Keep a Good Conscience 

I strive always to keep my conscience clear before God and man. (Acts 24:16) 

If a conscience has become corrupt, so that it is no longer functioning correctly, how can it become pure? If a conscience has become seared, it has become insensitive, like thick skin. How can it be made sensitive again? 

A good conscience is powered by the Spirit: If I take the batteries out of my alarm clock, it will not work. It is also set by the Word and cleansed by the blood of Jesus Christ. 

A good conscience is powered by the Holy Spirit 

When he comes, he will convict the world of guilt in regard to sin and righteousness and judgment. (John 16:8) 

Jesus is speaking about the Holy Spirit. When he comes, when he begins working in your life, what you can expect is that he awakens your conscience. When the Holy Spirit comes, he wakens you up to reality. Jesus describes that reality in three ways—sin, righteousness, and judgment: 

The Holy Spirit convicts of guilt in regard to sin 

The first work of the Holy Spirit is deeply disturbing—he activates your conscience. He brings you to a place where you see your own sin. 

The Holy Spirit convicts of guilt in regard to righteousness 

You don’t know what righteousness is until you know Jesus. When you get to know him, you see that his righteousness is so far beyond what you have at your best that you haven’t a hope of getting near him. 

The Holy Spirit convicts of guilt in regard to judgment  

The Holy Spirit convinces of sin and righteousness and judgment. A true Christian wants more of this, not less, because that is what authentic godliness is looking for.

It wants to know more of its own sin and more of God’s righteousness, so that it might embrace God’s mercy even more.  

A good conscience is set by the Word of God 

I have hidden your word in my heart that I might not sin against you. (Psalm 119:11) 

If the alarm clock is to function, it has to be powered, but it also has to be set. A good conscience is powered by the Spirit and set by the Word. Hiding God’s Word in your heart will train your conscience to sound the alarm and keep you from sin. 

Are you, like David, hiding God’s word in your heart? Or is it just flitting across your brain? When You hide God’s Word in your heart that Word shapes and strengthens your conscience. And a good conscience is your best defense against sin and temptation 

A good conscience is cleansed by the blood of Christ 

How much more, then, will the blood of Christ, who through the eternal Spirit offered himself unblemished to God, cleanse our consciences from acts that lead to death, so that we may serve the living God! (Hebrews 9:14) 

This is an amazing promise! Christ cleansing our consciences from acts that lead to death!  

How does he do it? By the blood of Christ, because on the cross he offered himself unblemished to God! He offered himself—his unblemished, perfect life—as a sacrifice to God for us on account of our sins. Therefore, he alone is able to cleanse our consciences through his blood.  

Your conscience may have been corrupted, even seared. Christ can make it good. That’s what redemption is all about. It is powered by the Spirit, set by the Word, and cleansed by the blood.
