Yah, we end up with a "we know it when we see it" type of definition of life. No one objects to chopping up and recombining DNA because it hurts DNA, so that's not the life. No one really denies that the fetus from moment of inception is alive. So supporters of abortion don't have a problem killing a living fetus; no one denies that the fetus is alive. I think those that are willing to kill babies in the womb have a conception of the baby as "not human" somehow, there is some point that they haven't come to that makes the fetus human. Since the Christian knows that God knows the baby in the womb, from the moment of conception and before as a person (Jeremiah 1:5 "Before I formed you in the womb I knew you);" the Christian sees it as an answered question . . . the secular thinker does not. Psalm 139 "You knit me together in my mother’s womb."
