I’ve been reading When I Don’t Desire God – How to Fight for Joy by John Piper. Here’s a quote I read this morning:

When Jesus says, “I am the bread of life;…whoever believes in me shall never thirst” (John 6:35), he is saying that “believing” in him includes a taste for the living water of his all-satisfying glory, so that the believing heart will never thirst again. That is, faith, having tasted the all-satisfying sweetness of the living Christ, will never forsake him in preference for the broken cisterns of the world. (Jer 2:13) There may be temporary strayings and backslidings. There may be great soul-conflict. But once the soul has truly tasted the water of life and the bread of heaven, it will never finally forsake the Lord.

He goes on to talk about how, in the western church, we have let go of Paul’s admonition to “Fight the good fight of faith. Take hold of the eternal life to which you were called” (1 Tim 6:12) by allowing a devil-may-care, cavalier, superficial attitude toward the ongoing, daily intensity of personal joy in Christ, because people do not believe that their eternal life depends on it.
