Both Paula and I always adored this song. While it's a secular song, I also think it's a very Christ-like song. God is aware of our needs, and wants to be able to meet them. It is sinful for us to fret about what we'll wear, or what we'll eat, or whether we will get this disease or that disease, because we are in God's hand.
