We find Jesus Himself answers our question on unforgivable sin in Mark 3:28-29 (NIV), “Truly I tell you, people can be forgiven all their sins and every slander they utter, but whoever blasphemes against the Holy Spirit will never be forgiven; they are guilty of an eternal sin.”  Here, Jesus states that all sins can be forgiven with one exception—blaspheming against the Holy Spirit. This is seeing God in action and ascribing His work as the work of Satan. This isn’t confusion, but rather deliberately saying that the things of God are a product of total evil.
