Yelsew,
If I did miss anything you referenced it is because I cannot believe how you continually find the cause of Christ's sinless nature in his humanity.
I have not once said the cause of Christ's "sinless nature" is in his humanity.
You have quite simply misread what I said based on your own bias. The evidence of that is in this sentence you wrote, "To put it into philosophical terms, He was not created, therefore, he could not sin." I tell you that, if he was not of "created" lineage, then he was not fully human! His flesh ONLY was human, and he, who is spirit, the true essence of Christ, was Divine. That is so unlike 100% human, or fully human.
This is the belief that I hold of man. MAN IS SPIRIT! I HAVE HELD THIS BELIEF FOR 40 PLUS YEARS, and in 40 years, I have seen nothing that is persuasive enough to cause me to rethink it. The difference between Jesus and all other men is that HIS spirit alone is derived from both human, and eternal spirit, half God the Father, half human. ALL 'OTHERS' OF MAN receive their spirit, human spirit (life), from
both of their parents, Jesus spirit was merely half human, if that much. If Jesus had not been conceived by Divine Spirit, then His spirit would have been "fully human" spirit too! And with fully human spirit he would most definitely have had a sin nature but he did not have a sin nature. He was tempted in all things common to man, but DID NOT SIN, BY HIS CHOICE! He is half human, and could easily have made the choice to sin. It is not because he could not sin, but because HE DID NOT SIN! His spirit was not receptive to sin like the fully human spirit is receptive to sin! Everything else was in place for him to have succumbed to temptation resulting in sin. IF He had sinned, He would not have been the WORTHY Lamb of God (Revelation 5), but because He faced temptation and DID NOT SIN, He was deemed WORTHY! SINLESSNESS is the Standard by which WORTHINESS is measured.
Because both ADAM and EVE ate of the tree of the knowledge of good and evil, both of their spirits were tainted by 'that knowledge', ALL of their progeny henceforth are likewise tainted hereditarily. Jesus is the exception, because the spirit of only one of his parents was so tainted. The spirit of the other 'parent' of Jesus was pure and holy. The virgin Mary I believe, had not sinned, she was pure and guiltless, therefore she had not activated the sin nature within her. Thus her spirit was clean and that is why God made her. God had to have a vessel through which His Son could be born, so He groomed Mary for the task, keeping her from sinning, which would thereby defile herself as to make her unworthy of being the mother of Jesus. NO, I do not believe that Mary remained sinless and therefore occupies a position of authority in Heaven! I believe she was fully human, sinless before the birth of Jesus, having sinned only after the birth of Jesus. I know, the Catholic Mary-olotrists are going to jump all over that, but so be it!
You said, "Plainly, he incarnated in the flesh from the seed of David but the blood he offered on the mercy seat was eternal. Otherwise, that blood would have been tainted." Jesus' body, thus his blood, was not eternal else he would have violated the plan that "it is appointed unto man once to die then the judgment". Yes, His blood was innocent of sin, but it was not intended to be eternal as it is part of the flesh which must die.
I trust this clears up any misgivings you may have regarding my beliefs of the essence of Jesus the Son of God. ALL of the mechanics were in place for Jesus the individual to have sinned, BUT HE CHOSE TO NOT SIN, just as we all must do, to become "righteous" after our new birth! We are commanded in scripture to be "holy", we are commanded to be righteous, we are commanded to choose to not sin. Yes, we are redeemed through our faith, but our actions prove our faith! Therefore, if we choose to continue in sin, to keep on sinning, we place our redemption in danger of being nullified, and we can lose our salvation on the basis of our choices. Not because of sin, for which the penalty has already been paid, but because of what sin does to our faith. We sin a little sin and 'get away with it', then we sin again, then again, then again. This process erodes our faith, putting blemishes in "our white robes". When the bridegroom comes to get us, we will not be ready and waiting, we will be left out because our apparel is filthy rags.
I trust that enough of the scriptural imagery brings to mind the scriptures from whence the imagery comes.
