John Piper, “Preaching as Worship:”

Jesus described faith this way in John 6:35 — “I am the bread of life; he who comes to me shall not hunger, and he who believes in me shall never thirst.”  Believing in Jesus means coming to him for the quenching of our soul’s thirst.  Faith in Christ is being satisfied with all that God is for us in Jesus.  When we experience that, we magnify the preciousness and worth of God, because God is most glorified in us when we are most satisfied in him — which means when we worship.
