We can be content with simplicity because the deepest most satisfying delights God gives us through creation are free gifts from nature and from loving relationships with people. After your basic needs are met, accumulated money begins to diminish your capacity for these pleasures rather than increase them. Buying things contributes absolutely nothing to the heart's capacity for joy.
John PiperProsperity cannot be a proof of God's favor, since it is what the devil promises to those who worship him. (Matt. 4:9)
John PiperMarriage is not mainly about prospering economically; it is mainly about displaying the covenant-keepin g love between Christ and his church. Knowing Christ is more important than making a living. Treasuring Christ is more important than bearing children. Being united to Christ by faith is a greater source of marital success than perfect sex and double-income prosperity.
