"In prayer, you ask for things and give thanks for things. Why? Because you recognize that God is the author and source of all the good that you have had already, and all the good that you hoped for in the future. This is the fundamental philosophy of Christian prayer. The prayer of a Christian is not an attempt to force God's hand, but a humble acknowledgement of helplessness and dependence. When we are on our knees, we know that it is not we who control the world; it is not in our power, therefore, to supply our needs by our own independent efforts; every good thing that we desire for ourselves and for others must be sought from God, and will come, if it comes at all, as a gift from his hands.... In effect, therefore, what we do every time we pray is to confess our own impotence and God's sovereignty. The very fact that a Christian prays is thus proof positive that he believes in the Lordship of his God."
