"Sometimes we hear it said that ten minutes on your knees will give you a truer, deeper, more operative knowledge of God than ten hours over your books. 'What!' is the appropriate response, 'than ten hours over your books, on your knees?'" (B.B. Warfield in 1911, "The Religious Life of Theological Students," in Mark Noll, ed., The Princeton Theology [Grand Rapids: Baker Book House, 1983], 263 cited in John Piper, Taste and See [Sisters, Oregon: Multnomah Publishers, 2005], 167).
