Introduction
In each of the Synoptic Gospels (Matthew, Mark, and Luke), as Jesus preached against the wicked and perverse generation in Israel, He made a statement that has puzzled many Christians even to this day. “Blasphemy against the Son of Man will be forgiven, but he who blasphemes against the Holy Spirit, that will not be forgiven.” Many people hear this and are terrified, “what if I committed the unforgivable sin? What if I have blasphemed against the Holy Spirit? How do I know my sins can be forgiven or not?”
If blasphemy against the Holy Spirit is an unbeliever speaking against the work of the Holy Spirit on earth, no one who doesn’t believe in Jesus could ever be forgiven. So, surely that is not it. But then what does this mean? What is this sin?
