If you don't mind me using the word, that is where you are drifting into heresy again. The Bible says that the blood of bulls and goats could never take away sins. Why? Only the blood of a perfect man could. It was the life of one man for another man. It was the life of a perfect man for an imperfect man. It was the life a just man for an unjust man. But he had to be a man. In order for him to be a man, he had to be clothed with flesh--mortal flesh; corruptible flesh. If he wasn't he wouldn't be a man. He would be something else--an alien, something, but not a man.standingfirminChrist said:Had Mary's egg been used, Jesus would have had her DNA. He would have been born with a corruptible body. This would defeat the purpose of Him coming into the world. That which is corruptible cannot redeem the corruptible.
Mary's egg could not have been used.
This man had to be a man, with the flesh of a man, corruptible flesh. A just man dying for unjust man. Second He had to be God. In being God he could die not just for one man, but for all men throughout all ages. He paid the penalty for all of our sins: past, present, and future because He is God. He lived, suffered, and died as man in a corruptible body like yours and mine. He rose again in an incorruptible and glorified body as we someday we will also have.
To pay that penalty he had to be perfect Man and perfect God: the God-Man. He could be nothing less.
