THE UNFORGIVABLE SIN
1. Core Meaning
The unforgivable sin—blasphemy against the Holy Spirit—is:
• A sin that cannot be forgiven
• A deliberate, persistent rejection of the Spirit’s work
• A conscious, hardened refusal of God’s grace
It is not a casual mistake, momentary doubt, or moral failure.
It is a settled posture of resisting the Spirit who brings forgiveness.

“Blasphemy against the Spirit will not be forgiven… in this age or the age to come.”
(Summary: Jesus emphasizes the eternal consequence of rejecting the Spirit.)
