Afterward Jesus found him in the temple, and said to him, "Behold, you are made well. Sin no more, so that nothing worse happens to you."
      (1.) The preparation of the medicine by an angel, who went down into the pool, and stirred the water. Angels are God's servants, and friends to mankind; and perhaps are more active in the removing of diseases (as evil angels in the inflicting of them) than we are aware of. Raphael, the apocryphal name of an angel, signifies medicina Dei--God's physic, or physician rather. See what mean offices the holy angels condescend to, for the good of men. If we would do the will of God as the angels do it, we must think nothing below us but sin. The troubling of the water was the signal given of the descent of the angel, as the going upon the tops of the mulberry trees was to David, and then they must bestir themselves. The waters of the sanctuary are then healing when they are put in motion. Ministers must stir up the gift that is in them. When they are cold and dull in their ministrations, the waters settle, and are not apt to heal. The angel descended, to stir the water, not daily, perhaps not frequently, but at a certain season; some think, at the three solemn feasts, to grace those solemnities; or, now and then, as Infinite Wisdom saw fit. God is a free agent in dispensing his favours.
