Some things God cannot give to a person until the person has prepared and proved his spirit by persistent prayer. Such praying cleans the house, cleanses the windows, hangs the curtains, sets the table, opens the door, until God says, “Lo! The house is ready. Now may the guest come in.”
—Harry Emerson Fosdick, The Meaning of Prayer
Here we see faith manifesting itself in works in the form of persistent prayer. Why continue to pray if you don’t think God is capable or willing to deliver? It just doesn’t make sense.
Often it seems like my prayers are so weak and powerless, and not necessary. But I know that the God I pray to is ominipotent, omniscient and loving. So even though I may not pray well, God will act perfectly.
