Can all sins be forgiven? Even the really super bad ones? Jesus is pretty clear on this. 1 John 1:9 states that if we confess our sins, He is faithful and just and will forgive us. There is no condition on this. It doesn’t matter how bad the sin is. He will forgive us.
But what about those tricky tricksters that try to point out that Jesus said there was an unforgivable sin? In Matthew 12:30-32, Jesus says He who is not with me is against me. Every sin against me will be forgiven, but not blasphemy against the Holy Spirit. Here, Jesus is talking about those who attribute His good works to Satan, basically denying who Jesus is. Only someone who is completely closed off from God’s love as to attribute Him as evil could commit this sin. It’s not something we could do by mistake or by a slip of the tongue. So tell those tricky tricksters that there is no sin greater than the cross.
This is not to say that there are no consequences for sin. In the Old Testament, atonement for sin required actual physical sacrifices, often in the form of an animal. In the New Testament, Jesus becomes the final sacrifice in his death on the cross. Even in His final moments on earth, Jesus was the ultimate picture of forgiveness, saying: forgive them, Father, for they know not what they do.
God knows the sin that you commit. He is not waiting for you to confess it so that He will know what you did. He already knows it. The act of confessing sin acknowledges our need for God. God is always ready to forgive you. Psalm 103:11-12 states as high as the heaven, so great is His love; as far as the east is from the west, so far have our transgressions been removed.
So what do we do with our forgiven life? God doesn’t forgive us so that we can just keep on doing whatever we want. John 13:35 says that all will know you are a disciple if you love one another. Romans 6:1-4 says that we are not to live in sin any longer; we have been buried with Jesus and we have also been raised to a new life. God’s forgiveness of us means that we have to life a different kind of life. We have been changed and need to act like it.
