I recall hearing one of my professors in seminary say that one of the best tests of a person's theology was the effect it has on one's prayers.
John PiperAll the different ways God has chosen to display his glory in creation and redemption seem to reach their culmination in the praises of his redeemed people. God governs the world with glory precisely that he might be admired, marvelled at, exalted and praised. The climax of his happiness is the delight he takes in the echoes of his excellence in the praises of the saints.
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.
John PiperThe gospel is the good news that the everlasting and ever-increasing joy of the never-boring, ever-satisfying Christ is ours freely and eternally by faith in the sin-forgiving death and hope-giving resurrection of Jesus Christ.
