You really bounce around on this list, Barry. You also continue to stand on a branch you’ve already cut out from under yourself. If God exists, but your argument is that he’s not the author of morality, then what makes you think you can challenge him against our human moral standards?
That said, I’m happy to answer this one.
If the biblical story of God is true, then God made all life, and it all belongs to him. And just as flowers and plants belong to the gardener who planted them to uproot/destroy as he sees fit (and he did not create them but merely nurtured them from their youngest moments, and it is only the natural order of plant being submissive to man that gives him this privilege).. how much more does life that was created ex nihilo by God belong to God to do with what he sees fit? There is nothing out of character or inconsistent with the biblical framework when God kills anyone or anything. If the Bible’s teachings are true, all creation is his to do with what he wishes. It is only by his sovereign mercy that he doesn’t wipe every one of us out immediately for the way even the best if us regularly live contrary to his desires, commands and plan.
So then why does God “go to the trouble” to ensoul them? Because every soul is precious, and though that soul may not live one earthly day outside a womb, the biblical view is that they will be treated to an eternity in the arms of their Heavenly Father. And for Him, creating each soul is not trouble; it is a pleasure and a joy. The sadness of a miscarriage is nothing in light of eternity. And should a grieving parent take the view of King David when God killed his son in the womb, they will be comforted with the notion of the day they join their child in paradise. As Paul said, “To live is Christ; to die is gain.”
I’ve responded extensively elsewhere on the topic of why it is wrong for a mother to choose, a father to encourage, or a doctor to perform, the child-murder of abortion. Those ensouled zygotes/fetus/babies are not theirs to do with what they please. They are God’s, however.
