My mum posed the same questions to me when I shared this with her. And look I could be wrong and am willing to be wrong but I'm not sure that I am. In some way His flesh seems different to ours, and maybe that difference is that His flesh was clothed with the Spirit of God like the First Adam's was until he sinned. In that way He was able to be tempted but without sin:
"For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh:" Romans 8:3
Regarding His death, recall that Jesus said:
"And he that sent me is with me: the Father hath not left me alone; for I do always those things that please him." John 8:29
But on the cross He said:
"And about the ninth hour Jesus cried with a loud voice, saying, Eli, Eli, lama sabachthani? that is to say, My God, my God, why hast thou forsaken me?" Matthew 27:46
Is it possible that His Flesh was unclothed at this point, enabling Him to die?
"Yet it pleased the LORD to bruise him; he hath put him to grief: when thou shalt make his soul an offering for sin, he shall see his seed, he shall prolong his days, and the pleasure of the LORD shall prosper in his hand." Isaiah 53:10
"All we like sheep have gone astray; we have turned every one to his own way; and the LORD hath laid on him the iniquity of us all." Isaiah 53:6
This was the revelation I had about the virgin birth. That the seed/sperm that formed the body of Jesus was not in any part put there by man but wholly conceived by God. The Body, the Soul and the Spirit.
"Who, being in the form of God, thought it not robbery to be equal with God: But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men: And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross." Philippians 2:6-8
"Ye are my witnesses, saith the LORD, and my servant whom I have chosen: that ye may know and believe me, and understand that I am he: before me there was no God formed (H3335), neither shall there be after me. I, even I, am the LORD; and beside me there is no saviour." Isaiah 43:10-11
Note that the word formed (H3335) is the same one used when God formed Adam from the dust of the ground:
"And the LORD God formed (H3335) man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul." Genesis 2:7
These are the thoughts I ponder when considering the body of Jesus. Maybe you might see an error in them that I can't. Maybe scriptures that I might not have considered? Coz I definitely can't think of any if there are some. I might share this with my mum as well and see if she comes up with anything.
It's really great sharing with you.
I'm enjoying the friendly discussion.
