A failure in our prayer life is generally a failure to know Jesus. "If you knew who was talking to you, you would ask me!" A prayerless Christian is like a bus driver trying alone to push a bus out of a rut because he doesn't know Clark Kent is on board.
And the implication is that those who do ask- Christians who spend time in prayer- do it because they see that God is a great Giver and that Christ is wise and merciful and powerful beyond measure. ...
The chief end of man is to glorify God. Therfore, when we become what God created us to be we become people of prayer.
John Piper
