The Lord Jesus Christ had no sin ... did not sin at all ... body, soul, spirit.
The Lord Jesus Christ was in all points tempted like as we are yet without sin (Heb 4:15).
The Lord Jesus Christ died because He laid His life down. He had no sin which would have resulted in death in Him. He was without sin.
John 10:15 As the Father knoweth me, even so know I the Father: and I lay down my life for the sheep.
You have provided absolutely no Scripture (chapter, verse) to support your assertion that the Lord Jesus Christ was "corruptible". All Scripture points to the fact that He was victorious over sin and death. Although satan tried, he was unsuccessful in his attempts to lure the Lord Jesus Christ.
These verses relate to descendants of Adam ... those begotten in the image and likeness of Adam (Gen 5:3).
The Lord Jesus Christ was the only begotten Son of God:
Luke 1:35 And the angel answered and said to her, “The Holy Spirit will come upon you, and the power of the Highest will overshadow you; therefore, also, that Holy One who is to be born will be called the Son of God.
Do not misapply verses written about those who were descended from Adam.
The Lord Jesus Christ did not fully partake ... He only took part:
Hebrews 2:14 Forasmuch then as the children are partakers of flesh and blood, he also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil;
As I pointed out in Post #462, Jesus' flesh profits us:
Hebrews 10:
19 Having therefore, brethren, boldness to enter into the holiest by the blood of Jesus,
20 By a new and living way, which he hath consecrated for us, through the veil, that is to say, his flesh;
21 And having an high priest over the house of God;
22 Let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience, and our bodies washed with pure water.
Do you see that the new and living way in which we draw near to God is through the veil, that is to say, his flesh?
When you insist that Jesus' flesh was corrupt, you cut off our ability to draw near with a true heart.
You must come to understand that there was absolutely no corruptness in Jesus ... None ... "nada. zip" if you want to draw near with a true heart ... having our hearts sprinkled from an evil conscience, and our bodies washed with pure water.
If there was any blemish or spot in Jesus, our bodies were not washed with pure water, our hearts were not sprinkled from an evil conscience. We are still far off.
No one here disagrees with this, garee.
All agree that we are born again because it is God Who works within us ... Eph 2:8-9 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast.
All agree that the inward man is renewed day by day ... 2 Cor 4:16 For which cause we faint not; but though our outward man perish, yet the inward man is renewed day by day.
And again, I would caution you against misapplication of what Scripture indicates concerning those who are descended from Adam (after the image/likeness of Adam) and your claim that because Jesus took part, that means His flesh was corrupt.
Learn to differentiate between what is written about us (all of mankind ... image/likeness of Adam) and what is written about Him (the only begotten Son of God ... not image/likeness of Adam).
