I have never found any man so religious and godly, but that he felt sometimes a withdrawal of the divine favour, and lack of fervour. No saint was ever so filled with rapture, so enlightened, but that sooner or later he was tempted. For he is not worthy of the great vision of God, who, for God’s sake, hath not been exercised by some temptation. For temptation is wont to go before as a sign of the comfort which shall follow, and heavenly comfort is promised to those who are proved by temptation. As it is written, “To him that overcometh I will give to eat of the tree of life.”
Divine comfort is given that a man may be stronger to bear adversities. And temptation followeth, lest he be lifted up because of the benefit. The devil sleepeth not; thy flesh is not yet dead; therefore, cease thou not to make thyself ready unto the battle, for enemies stand on thy right hand and on thy left, and they are never at rest.
