John Bunyan

“This is the right calling of God, Father; and not as many do, to say in a babbling way the Lord's prayer by heart. No, here is the life of prayer, when in or with the Spirit, a man being made sensible of sin and how to come to the Lord for mercy, he comes, I say, in the strength of the Spirit, and crieth, Father. That one word spoken in faith, is better than a thousand prayers in a formal, cold, lukewarm way.”
