David's life was characterized by prayer. Prayer was the essence of David's life and his genius, as it is ours. We have this access to God, this intimacy with Him, this opportunity to receive all that the heart of God has stored up for us. It is the means by which we receive God's gifts, the means by which everything is done. David teaches us to pray.
Prayer is worship.
Our praying should be full of adoration, affection, and fondness for God that He is who He is, that He created us in order to have someone on whom He could shower His love, that He stretched out His arms on the cross, and that He intends, in the fullest sense, to make whole men and women out of us. In worship, as the old word worth-ship implies, we declare what we value the most. It is one of the best ways in the world to love God. Prayer is the highest expression of our dependence on God. It is asking for what we want.
