Psalm 139:13-14

13 For you formed my inward parts;
you knitted me together in my mother’s womb.
14 I praise you, for I am fearfully and wonderfully made.
Wonderful are your works;
my soul knows it very well.

Here is a fascinating look at the development of a baby in the womb, from conception to birth. The excerpt from the lecture is very interesting from a Christian perspective.
