A Christian is not a person who believes in his head the teachings of the Bible. Satan believes in his head the teachings of the Bible! A Christian is a person who has died with Christ, whose stiff neck has been broken, whose brazen forehead has been shattered, whose stony heart has been crushed, whose pride has been slain, and whose life is now mastered by Jesus Christ.
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 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.
