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 PiperThe very longing for contentment that ought to drive us to simplicity of life and labors of love contents itself instead with the broken cisterns of prosperity and comfort.
John PiperSuffering in the path of Christian obedience, with joy - because the steadfast love of the Lord is better than life (Psalm 63:3) - is the clearest display of the worth of God in our lives. Therefore, faith-filled suffering is essential in this world for the most intense, authentic worship. When we are most satisfied with God in suffering, he will be most glorified in us in worship. Our problem is not styles of music. Our problem is styles of life. When we embrace more affliction for the worth of Christ, there will be more fruit in the worship of Christ.
John Piper
