No one really understands prayer, but prayer is an important practice of the church.
We pray not to convince God to do something God should do anyway. God does not seem to be pushing buttons.
We pray not to receive blessings for ourselves when others do not have the same blessing we seek. It's not just about us.
Praying is an act of faith. Praying is also a way we become a part of a community which is aware of our life concerns.
No one really understands prayer, but we pray for each other and the world.
