The Bible says only one sin is unforgivable–and that is the sin of refusing God's forgiveness. If we turn our backs on God and refuse to have anything to do with Him, then we will eventually pay the consequences for our stubbornness.
But it doesn't need to be this way! God is our loving Heavenly Father, and He yearns to forgive us and welcome us back to Himself. He loves us so much that He has done everything possible to win us back, by sending His only Son into the world to pay the price for our sins. We deserve to die for our sins–but when Christ died on the cross, all our sins were placed in Him, and He took the punishment we deserve. The Bible says, "God demonstrates his own love for us in this: While we were still sinners, Christ died for us" (Romans 5:8).
Jesus warned, "Whoever blasphemes against the Holy Spirit will never be forgiven; he is guilty of an eternal sin" (Mark 3:29). Blaspheming the Holy Spirit simply means saying that what the Holy Spirit says in the Scriptures about Christ is false. When we do that, we reject Christ and all He has done for us–and we are committing the only unforgivable sin.
May that not happen to you, or to anyone else reading this column. Instead, turn to Christ and by a simple prayer of faith invite Him into your life today. Jesus' promise is for you: "Whoever comes to me I will never drive away" (John 6:37).
