So it's your addition to the meaning of a Koine Greek word! Tsk, tsk, tsk.

[Mrs. Don-o]

Well, it's actually very simple and in keeping with the Koine. In fact, wel in keeping with the whole of Scripture.

When mercy fails, it can logically fail either on the side of the giver or on the part of the receiver. We already know from other Scriptures that there can be no failure on God's part: there is no limit or no defect in His mercy, which is infinite and endures forever. Therefore the defect must be on the part of the receiver.

And the connection with blasphemy? A person who blasphemes against the Holy Spirit so disposes his soul that he does not receive mercy or the Source of Mercy: he rejects it.

So we can see that the Unforgivable Sn is unforgivable because of final impenitence (on the part of the sinner) and not mercy-deficiency (on the part of the Holy Spirit.)
