Until your soul has a thirst for Christ as the bread of life and the living water, you will use Christ for what your soul thirsts after. Many people who claim to have saving faith simply use Christ to get what they really want, which is not Christ but His gifts (escape from hell, peace of mind, health of body, a better marriage, a social network, etc.). We are saved by coming to Christ not only as our deliverer but also as our treasure.
John Piper, Let the Nations Be Glad, pp. 211-212
