An excerpt from Psalm 139. The Lord is the master of conception and new life:-
For you formed my inmost being. You knit me together in my mother's womb. I will give thanks to you, for I am fearfully and wonderfully made. Your works are wonderful. My soul knows that very well. My frame wasn't hidden from you, when I was made in secret, woven together in the depths of the earth. Your eyes saw my body. In your book they were all written, the days that were ordained for me, when as yet there were none of them. How precious to me are your thoughts, God! How vast is the sum of them!
Psalm 139: 13-17 (NHEB)
