After committing adultery and then having the woman’s husband murdered, King David wondered if he had committed the unpardonable sin. “Don’t cast me away from Thy presence, God!” he begs, fearful that his act was so heinous that he was beyond God’s redemption. Christians have long debated what the unpardonable sin is. Some Christians even live in fear, terrified that they may have committed the unpardonable sin and that God has already separated Himself from them.
Now let’s stop here a moment. If you worry that you have committed the unpardonable sin, it’s one of the clearest signs you have not. The very fact that you are bothered by your sinfulness shows that the Holy Spirit has not abandoned you!
The only unpardonable sin is total rejection of Jesus Christ. The one thing God can’t forgive is when we reject His Son all our lives. God will not forgive us for rejecting the incredible thing His Son did for us, paying the penalty so that our sins could be washed away when we have repentant faith in Him.
Whatever evil you have done and however bad you feel you are, God offers His forgiveness in Christ.
