I actually thought I might get the last word when I posted, darn you guys

First we certainly must address the elephant in the room, the long garments certainly had a designer label, and although it was not a faux fir, it was most certainly made in the greenest of standards. The animal, who unknowingly volunteered, was proud to have their skin turned into garments that would go down throughout history as the very first clothing fashion statement, and as the only divinely made fur ever made. Unfortunately the label 'divinely made' never made it far, as nobody could recreate the quality, and thus the 'manmade' label soon became the hottest trend. I wonder if it was a skunk, to remind the pair of what a stinky decision they made...
“. . .And Jehovah God proceeded to make long garments of skin for Adam and for his wife and to clothe them.. . .”
Ge 3:21
Now to less serious matters..jk of course.
I don't think Adams sin would constitute as blasphemy against the holy spirit for the reason that I don't think he committed the sin with ill intent against God. Satan most certainly committed blasphemy when he lied to Eve for dishonest gain. Never once did Adam speak out against God.
The fact that he wasn't deceived, yet chose to sin, does not itself constitute blasphemy against the holy spirit. In fact, if we look at the verse Kevin provided, it actually strengthens my argument in that
'every sort of sin and blasphemy will be forgiven men'. All sin goes contrary to Gods spirit, but not all sin is
against Gods spirit(blasphemy),
in that it is committed with a wicked heart, with malice as its intent. What's the difference? Blasphemy against the Holy Spirit must have its source in evil thought and is a reflection of such through the words of a person, such as Satan in Eden, or when Judas did it for evil gain when he agreed to betray Jesus, or when the Pharisees accused Jesus of blasphemy they were guilty of it themselves by doing so. Because they allowed their hearts to be hardened, they developed wicked hearts sourced by sin that produced evil intentions
against the Holy Spirit. Again if we are to compare the sin of Satan, and the sin of Adam, the two most certainly do not equate with one another as regards intent to go against Gods purpose. Yes, they both sinned, and went contrary to Gods purpose, however the intention for doing so was completely different. One had a wicked heart, the other had a selfish one. The difference is what makes one sin unforgivable, and the other just so. Prior to Adams sin, he most certainly never had an evil thought against God, therefore his sin was not sourced with evil intent as Satans was, but rather, as I have pointed out many times on here, was motivated/sourced by his love for Eve.
The scripture that Barnaby alludes to suggests as much:
“. . .YOU are from YOUR father the Devil, and YOU wish to do the desires of YOUR father. That one was a manslayer when he began, and he did not stand fast in the truth, because truth is not in him. When he speaks the lie, he speaks according to his own disposition, because he is a liar and the father of [the lie]. . .” Joh 8:44
“. . .He who carries on sin originates with the Devil, because the Devil has been sinning from [the] beginning. For this purpose the Son of God was made manifest, namely, to break up the works of the Devil.” 1Jo 3:8
Because the sin of blasphemy must reside within a wicked heart, unless Adam himself had a wicked heart to begin with when he sinned, his sin cannot be constituted as blasphemy against the Holy Spirit. There is nothing in the scriptures to suggest such a thing, but in fact just the opposite, as he was performing flawlessly in thought and deed, up unto the moment of sin. It is for this very reason that his sin must be sourced in love for his wife, not in a wicked heart such as Satan had, and that makes
all the difference in the world.
Something else that occurred to me is the statement made by John in that 'he who carries on sin
originates with the devil'. If Adam is the source of our sin, why is it that John does not mention him as the source, but rather he goes beyond Adam to the source of evil, the devil? Because
evil intention is sourced, or originates, from Satan.
Although Adam failed to make a right choice, sin came through him, but not from him. That is a distinction that must be understood in order to fully comprehend what happened, as he is not the father/source of the lie, of malice, of intent to deceive, of hatred against God, Satan is.
“. . .That is why, just as through one man sin entered into the world and death through sin, and thus death spread to all men because they had all sinned—. 13 For until the Law sin was in the world, but sin is not charged against anyone when there is no law. 14 Nevertheless, death ruled as king from Adam down to Moses, even over those who had not sinned after the likeness of the transgression by Adam, who bears a resemblance to him that was to come.” Ro 5:12-14
“. . .For just as through the disobedience of the one man many were constituted sinners, likewise also through the obedience of the one [person] many will be constituted righteous. . .” Ro 5:19
Sin did not come from Adam, but through Adam, from Satan. Just as salvation does not come from Jesus, but through Jesus, from Jehovah.
It is a perfect balance which had to be restored in order for Gods purpose to continue.
“. . .to [the] only God our Savior through Jesus Christ our Lord, be glory, majesty, might and authority for all past eternity and now and into all eternity. . . .” Jude 25
