The unforgivable sin (blasphemy against the Holy Spirit) — Mike is not fully settled on the interpretation but identifies the key exegetical questions: is it calling the work of the Holy Spirit the work of Satan, a continuous act of resistance, or any negative speech about the Spirit?

The context of Jesus' statement is that he had just cast out a demon and the Pharisees attributed it to Satan. Jesus warns that speaking against the Son of Man can be forgiven but blasphemy against the Holy Spirit cannot. Mike identifies three interpretive options: (1) it is specifically calling the Spirit's work demonic, (2) it is a continual pattern of resisting the Spirit, or (3) it is any negative speech about the Holy Spirit. Mike declines to take a firm position, saying he has studied the passage but does not feel settled enough to prescribe a view.
