When I think of my birthday, it reminds me that I am God's creation. Psalm 139 reminds me of this:
13 For you created my inmost being;
you knit me together in my mother's womb.
14 I praise you because I am fearfully and wonderfully made;
your works are wonderful,
I know that full well.
15 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,
16 your eyes saw my unformed body.
All the days ordained for me
were written in your book
before one of them came to be.
Join me in my praise to the LORD for one more year!
