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 PiperFight for us, O God, that we not drift numb and blind and foolish into vain and empty excitements. Life is too short, too precious, too painful to waste on worldly bubbles that burst. Heaven is too great, hell is too horrible, eternity is too long that we should putter around on the porch of eternity.
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.
John PiperThe call of God creates sight in us. It's the work of God in our hearts to awaken us before his word.
