On a personal note, this Friday and Sunday I witnessed the birth and then the second birth of my seventh living child, Grace Katherine. What a joy! Having children most certainly makes me a happy man! And that is precisely what God says it does:
Behold, children are a heritage from the LORD,I am a very happy man indeed. Praise be to God!
The fruit of the womb is a reward.
Like arrows in the hand of a warrior,
So are the children of one’s youth.
Happy is the man who has his quiver full of them.
