The key to praying with power is to become the kind of persons who do not use God for our ends but are utterly devoted to being used for His ends.
John PiperThe infinite reservoir of future grace is flowing back through the present into the ever-growing pool of past grace. The inexhaustible reservoir is invisible except through the promises. But the ever-enlarging pool of past grace is visible; and God means for the certainty and beauty and depth to strengthen our faith in future grace.
John PiperI am not a missionary, but I have wanted my life to count for the unreached peoples of the world.
John PiperEvery criticism or slight against you, warranted or not, received or endured humbly, is written in heaven for your reward.
