Why Pray?

If God is sovereign over all as Ephesians 1:11 say He is, then why pray?

John Piper wrote an article back in 1976 answering two questions:

1. “Why pray for anyone’s conversion if God has chosen before the foundation of the world who will be his sons?”
…..
2. If someone now says, “O.K., granted that a person’s conversion is ultimately determined by God’ I still don’t see the point of your prayer. If God chose before the foundation of the world who would be converted, what function does your prayer have?”

Take some time and go read the article. It is pretty short, and it is eye-opening.
