Swindoll's comment makes me think of a quote I came across by August Neander which impressed me so much I made it into a bookmark I keep in my Bible: "God reveals Himself in His Word, as He does in His works. In both we see a self-revealing, self-concealing God, who makes Himself known only to those who earnestly seek Him; in both we find stimulants to faith and occasions for unbelief; in both we find contradictions, whose higher harmony is hidden, except from him who gives up his whole mind in reverence; in both, in a word, it is a law of revelation that the heart of man should be tested in receiving it; and that in the spiritual life, as well as in the bodily, man must eat his bread in the sweat of his brow."
