What died when Adam sinned?
I'll say his spiritual life if one agrees that when a man is whole he is body, soul, and spirit.
Since God had to put his spirit upon certain men in the OT there is the implication that since Adam man has been born only body and soul with John the Baptist being the single exception, being filled with holy spirit from his mother's womb.
Natural man of body and soul is absent God's spirit. That spirit cannot be given by man nor can it be taken or regulated by man.
So in reality, I don't think the question is really relevant.
Do I need to repeat that I don't think abortions should happen?
Nope. I understand that. I'm doing what P-Marlowe challenged: Attempting to find a biblical basis for "life" beginning prior to blood forming.
I've never worked on it before.
Yet, I've no doubt it is the the truth based on the Jeremiah verse in which God says that He knew Jeremiah before Jeremiah was formed in the womb.
Also, Christ left His estate with God and took the form of a human through the mechanism of the Holy Spirit overshadowing Mary. Her "seed" was to bruise the head of the serpent, therefore, Mary did contribute her seed in the equation. That seed was at one point pre-blood, but it was also the incarnated, second person of the Trinity.
Are we saying it lacked "life" EVEN THOUGH it was the eternal second person of the blessed Trinity?
