In some, converting light is like a glorious brightness suddenly shining upon a person, and all around him: they are in a remarkable manner brought out of darkness into marvelous light. In many others it has been like the dawning of the day, when at first but a little light appears, and it may be presently hid with a cloud; and then it appears again, and shines a little brighter, and gradually increases, with intervening darkness, till at length it breaks forth more clearly from behind the clouds.
