David, mighty in faith and deed, was nonetheless much like any one of us; a human being with precisely the same needs, desires, and weaknesses we all share. As we emulate him, the theme of Psalm 25 will come to pass in our lives: Those who fear the LORD will be led by the LORD!
Prayer is infinite ignorance trusting to the wisdom of God. Prayer is the voice of need crying out to Him who is inexhaustible in resources. Prayer is helplessness reposing with childlike confidence on the word of its Father in heaven. Prayer is but the verbal expression of the heart of perfect confidence in the infinite wisdom, the power and the riches of Almighty God, who has placed at our command in prayer everything we need.
