It is said that no words of Jesus have caused more anguish and misunderstanding than these words about the unpardonable sin. What is this sin? Can I know whether I have committed it? An important step toward answering this question is understanding what sin is, according to the Scriptures. We tend to think of sins in the plural as individual acts. The Bible speaks of sin in the singular as a state of mind or a way of being. It is enmity with God. All sins as individual acts can be forgiven, Jesus says. But when, in enmity toward God, we definitely rely on ourselves and reject God completely, there is no forgiveness possible. Wondering and worrying about this sin, therefore, is probably the best sign that it has not happened to us. The unforgiveable sin is a paradox: On the one hand, it is not a passive sin; it requires a specific intentional action. So if you're not worried about having committed it, then you probably haven't. On the other hand, it is a sin that requires a total emotional and spiritual disconnection from God and everything that is important to God. So if you are worried about having committed it, then you probably haven't. The Holy Spirit is the one who makes us aware of our sinfulness, who makes us thirst for forgiveness, and who announces the gift of forgiveness to us in God's word. Even our worries and anxieties can be signs of the fact that he is at work in us.
