"A holy boldness, a chastened familiarity, is the true spirit of right prayer. It was said of Luther that, when he prayed, it was with as much reverence as if he were praying to an infinite God, and with as much familiarity as if he were speaking to his nearest friend." - G. S. Bowes, as quoted in Spurgeon's Sermon Notes
