258957047294288047_Y6z2NNBf_fPsalm 139:13-16 is the go-to Bible passage 90% of the time for pastors planning sermons on the pro-life issue. In it, David eloquently describes human life as a continuum that begins at conception, with God as our Creator:

For you created my inmost being; you knit me together in my mother’s womb. I praise you because I am fearfully and wonderfully made; your works are wonderful, I know that full well. My frame was not hidden from you when I was made in the secret place. When I was woven together in the depths of the earth, your eyes saw my unformed body. All the days ordained for me were written in your book before one of them came to be.
