Why would God not forgive this particular sin, even if someone later felt remorse?
The unforgivable nature of blasphemy against the Spirit isn't about an arbitrary rule, but a consequence. When someone consistently and deliberately attributes the Holy Spirit’s work to demonic power, they are essentially rejecting the very means God uses to bring people to Himself. This creates a spiritual hardening, a complete resistance to the Spirit’s conviction and call. In this state, the person loses the capacity to repent and believe, making forgiveness, which is received through repentance and faith, impossible for . It’s a state of final, self-imposed alienation from God.
