Scripture is clear that Christ took upon Himself the nature of a man, Abrahams nature. Heb 2:16 For verily he took not on him the nature of angels; but he took on him the seed of Abraham. Possibly DHK would like to make one small exception to the sinful nature he attests to with Abraham, since Christ took on his seed and as such his nature.
Why not study the verse first. You are making the verse mean something that it does not mean. Look at it in another translation:
Hebrews 2:16 For most assuredly, not to angels does he give help, but he gives help to the seed of Abraham. (WEB)
"To lay hold of" means to lay hold of with intent to help. Christ came not to give help to the angels but to give help to the seed of Abraham, that is the descendants of Abraham. It is not speaking of him taking on anyone's flesh. You have the wrong Scripture, the wrong meaning.
You will have to do better than that. Your interpretation of this verse is way off. It has nothing to do with the nature of Christ.
