The Bible says that God is able to do exceedingly abundantly above what we ask or think. By this it means that there no request from us that will impossible for God to grant. His ability extends far beyond our imagination. It does, however, mean that God will always do above what we ask or think. If so, we would be receiving from God even when we did not ask for anything. Then what is the use of prayer? Rather, you will receive according to your faith.
