Blasphemy of the Holy Spirit and the Mark of the Beast

 "Therefore I say to you, every sin and blasphemy will be forgiven men, but the blasphemy against the Spirit will not be forgiven men.  Anyone who speaks a word against the Son of Man, it will be forgiven him; but whoever speaks against the Holy Spirit, it will not be forgiven him, either in this age or in the age to come." Matthew 12:31-32

I would be open to the idea of a consequence without remedy for the Christian that's not an eternal-life-issue, but what would that be? Could it be like being called "least" in the kingdom, as in Matthew 5:19: "Whoever therefore breaks one of the least of these commandments, and teaches men so, shall be called least in the kingdom of heaven...".   Such a view would safeguard against the idea that one could be saved and yet later commit this blasphemy and lose their salvation.  

However,  Mark 3:29 speaks of the blasphemy of the Holy Spirit as having "eternal condemnation" as a result: "Assuredly, I say to you, all sins will be forgiven the sons of men, and whatever blasphemies they may utter;  but he who blasphemes against the Holy Spirit never has forgiveness, but is subject to eternal condemnation" Mark 3:28-29

I have thought that there is a similarity between this blasphemy of the Holy Spirit and receiving the "mark of the Beast," which would be an eternal life issue.  For if one takes the mark of the Beast, they are eternally condemned, according to Revelation 14:9-11 (see below).  But what is it about the mark that this could be the case?  Maybe --however it is received by an individual--it involves a hardness of heart that can't respond to God, a kind of point of no return.  Maybe that's the case with blasphemy of the Holy Spirit: it involves a hardness of heart that will never respond to the truth, even after undeniable evidence, such as the Jews who saw the miracles of Jesus and yet rejected that they were the working of God.  I don't know if this is the solution, but I see this similarity, because whatever the "Mark" will be, if you receive it, there's no remedy, just like the blasphemy of the Holy Spirit.  

"Then a third angel followed them, saying with a loud voice, 'If anyone worships the beast and his image, and receives his mark on his forehead or on his hand,  he himself shall also drink of the wine of the wrath of God, which is poured out full strength into the cup of His indignation. He shall be tormented with fire and brimstone in the presence of the holy angels and in the presence of the Lamb.  And the smoke of their torment ascends forever and ever; and they have no rest day or night, who worship the beast and his image, and whoever receives the mark of his name.'" Revelation 14:9-11

And if I cast out demons by Beelzebub, by whom do your sons cast them out? Therefore they shall be your judges. But if I cast out demons by the Spirit of God, surely the kingdom of God has come upon you. Matthew 12:27-28
