What does it mean to “blaspheme the Holy Spirit” today?

In the Gospel of Mark, Chapter 3, the blasphemy that Jesus accused the Jewish leadership of committing involved their accusation that Jesus’ miracles were the result of demonic possession or that Jesus was performing these miracles by the power of Satan when Jesus was performing those miracles by the power and anointing of the divine Holy Spirit; therefore, they had blasphemed the Holy Spirit by calling Him Satan; consider this, it was these in the Jewish audience who had personally witnessed Messiah in the flesh and were eye witnesses of Messiah’s miracles and the work of the Spirit; therefore, they would NEVER be forgiven for this most atrocious demonically inspired accusation and insult.

It’s important to note that this eternal condemnation was directed ONLY at those in this unique context as Jesus walked upon this Earth in flesh and said eternal condemnation is NOT possible today as we are NOT in said Biblical context as Jesus is NOT among the masses performing, openly, the miracles He performed in that Day; therefore, blasphemy in the context of Mark 3 is NOT possible today.

Lastly, it’s important to note that the ONLY sin that will never be forgiven is rejecting the call of the Holy Spirit on one’s life to repent and believe the Gospel; that is, if one dies in an unrepentant state, they will NEVER be forgiven as Judgment/condemnation is their future. If one dies rejecting Jesus, they have blasphemed the Sprit by calling Him a liar concerning the precepts of the Gospel; therefore, in today’s context, blasphemy of the Spirit is “rejecting Jesus as Messiah.”
