I am far less willing to take the whole New Testament on faith, because much of it never makes any claims to divine inspiration. There is a huge difference between designating Exodus the second book of Gods holy law, delivered through the divinely inspired prophets, and Paul advising a little wine for Timothys indisgestion, or penning a personal plea with which a fugitive slave can seek clemency on voluntary return to his master. Yet even the Didache fell short of the high canon standards Timothy and Philemon somehow met. I fault none of them, but neither do I hang my spiritual hat on their entirety, at least not automatically.

Setting all that aside though, we would still have a variation of the same basic problem: Forbidding us to "kill a child in the womb" does not establish when it becomes a child. Until/unless it does, the prohibition applies no more to a fetus than to a cancerous lung. Egg cells are alive with or without fertilization, yet billions of womens bodies kill them monthly, and no one (including God) calls it murder. The issue is not whether murder should be legal, but when there is a person TO murder.
