If we have no zeal for the glory of God our mercy must be superficial, man-centred human improvement with no eternal significance. And if our zeal for the glory of God is not a revelling in his mercy, than our so-called zeal, in spite of all its protests, is our of touch with God and hypocritical.
John PiperIf my life was to have a single, all-satisfying, unifying passion, it would have to be God's passion.
John PiperGod is pursuing with omnipotent passion a worldwide purpose of gathering joyful worshipers for Himself from every tribe and tongue and people and nation. He has an inexhaustible enthusiasm for the supremacy of His name among the nations. Therefore, let us bring our affections into line with His, and, for the sake of His name, let us renounce the quest for worldly comforts and join His global purpose.
John PiperIt is evil to justify killing (unborn babies) by the happy outcome of eternity for the one killed. This same justification could be used to justify killing one-year olds, or any heaven-bound believer for that matter. The Bible asks the question: "Shall we sin that grace may abound?" (Romans 6:1) And: "Shall we do evil that good may come?" (Romans 3:8). In both cases the answer is a resounding NO. It is presumption to step into God's place and try to make the assignments to heaven or to hell. Our duty is to obey God, not to play God.
