“ When one man that was in anxiety of mind, often wavering between fear and hope, did once, being oppressed with grief, humbly prostrate himself in a church before the altar in prayer, and said within himself, “Oh, if I knew that I should yet persevere!” he presently heard within him and answer from God, which said, “What if thou didst know it, what wouldest thou do? Do now what thou wouldest do then, and thou shalt be secure.”
And being herewith comforted and strengthened, he committed himself wholly to the will of God, and that troubling anxiety ceased:
Neither had he any mind to search curiously any further, to know what should befall him; but rather labored to understand what was the perfect and acceptable will of God, for the beginning and accomplishing of every good work. ”
