So, what is the unforgivable sin? Let me tell you what it is NOT. It is not murder. Moses was a murderer and he’ll be in heaven. The unforgivable sin is not adultery. King David committed adultery and God forgave him. It’s not divorce. The woman at the well had multiple divorces and she was forgiven. It is not suicide. Suicide is self-murder and it is no different from homicide—both are forgivable. Once you are a Christian, you don’t have to confess every single sin you commit in order to go to heaven. We confess our sins to stay in fellowship with God, but when you surrender your life to Christ, every past sin you’ve committed and every future sin you will ever commit is covered by the blood of Jesus Christ.
