From "Tested by Fire" - John Piper

"Suffering 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."
