Jesus came in sinful fallen flesh.
concerning his Son Jesus Christ our Lord, which was made of the seed of David according to the flesh;
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:
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;
Jesus had sinful flesh and He gained the victory over the devil. He who seemed weak, destroyed the devil when He died on the cross.
Oh the love of God!
