Sin is what you do when your heart is not satisfied with God. No one sins out of duty. We sin because it holds out some promise of happiness.
John PiperA saving knowledge of Christ crucified and risen is not the mere result of right reasoning about historical facts. It is the result of spiritual illumination to see those facts for what they really are: a revelation of the truth and glory of God in the face of Christ-who is the same yesterday today and forever.
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.
