We need also to be careful about our petitions in yet another way by remembering to whom we pray and His omniscience. C. S. Lewis observed, "I've heard a man offer a prayer for a sick person which really amounted to a diagnosis followed by advice as to how God should treat the patient." (Letters to Malcolm: Chiefly on Prayer [New York: Harcourt, Brace, and World], p. 20.) It is not condescension but humility that is required as we approach our Father in heaven.
