Our spirit life begins in the pre-existence with god. We wait for our time to come to earth. Our spirit takes shape within that body upon birth. I would say that an abortion does end a life but not necessarily for that spirit that would have inherited that body. There will be other bodies.
I really think you should rethink your last couple of sentences because they sound quite absurd. First of all, there is no human life in a body if that body has no soul (spirit) present within. So you can’t say that abortion ends a life if you believe the soul doesn’t enter the body until birth. Secondly, to say there will be other bodies for that soul, well, that’s just plain bizarre.
And if you then fall back on the position that we don’t really know when the soul enters the body, as other Mormons may say, then would it not be prudent to assume that this event occurs at conception in order to take the most conservative stance in the protection and sanctity of human life? If we don’t
know, shouldn’t we then logically take the most conservative position rather than hope human life begins at some later time and take the risk of being wrong?
As far as pre-existence goes, Mormons run a mile with a couple of scriptures that in no way indicate the Jews believed in pre-existence, or that we existed in heaven with God prior to our birth. “Before I formed you in your mother’s womb I knew you” does not mean that there was a pre-existence. Look at it this way–God never says that* we knew Him* before we were born. So what do we learn from this? Remember that God, as the creator of the universe, exists apart from time and space, not within time and space. For him there is no time, and in that context the verse makes perfect sense. He knows all that was, all that is, and all that will be–all at the same time! He sees his creation all at once, which is something we cannot grasp with our limited human understanding.
I tell you my friend–if you really believe that the soul doesn’t enter the body until birth, then you are in the same camp as even the most militant pro-abortionists, because they believe the
same thing. Allowing yourself to believe that an unborn baby has no soul, but is merely a bunch of flesh and bone, is what makes the acceptance of unlimited abortion possible. Even if the Mormons insist on the belief of the pre-existence, I am rather shocked that they wouldn’t say that a pre-existent soul is placed within the body immediately at conception.
