“Let us draw near to God with a sincere heart and with the full assurance that faith brings, having our hearts sprinkled to cleanse us from a guilty conscience.” (Heb. 10:22a NIV)
When I was about ten years old, I went to a five-and-dime store with my dad. There were shelves full of toys. When nobody was looking, I slipped a small toy into my pocket and walked out without paying for it.
Almost immediately, my conscience began to torment me. That night I couldn’t sleep. I imagined the worst—being arrested, going to jail, being exposed as a thief. The next day, when my dad returned to the same store, I went with him and secretly put the toy back on the shelf. Instantly, I felt relief and peace.
God has built something into us called a conscience.
Webster’s defines conscience as “a knowledge or sense of right and wrong, with a compulsion to do right… that leads to feelings of guilt.”
An old Indian once said, “A conscience is a wheel within your heart with sharp arrows pointing outward. When you do wrong, the wheel turns and the arrows hurt you. But if you keep doing wrong, the points break off.”
The Bible warns that this can happen:
“Speaking lies in hypocrisy, having their conscience seared with a hot iron.” (1 Tim. 4:2)
A neglected conscience can become dull. A violated conscience can become hardened. But a conscience cleansed by Christ becomes peaceful and free.
That’s why Scripture urges us:
“Having a good conscience…” (1 Peter 3:16)
“Keeping faith and a good conscience…” (1 Timothy 1:19)
And Hebrews reminds us that only Jesus can truly cleanse it.
Therefore
Don’t ignore your conscience—and don’t try to numb it. When it speaks, let it lead you to Christ. His blood doesn’t just forgive your sins; it cleanses your conscience, giving you real peace and full assurance before God.
“How much more shall the blood of Christ… cleanse your conscience from dead works to serve the living God?” (Hebrews 9:14)
