John Chrysostom

"And let us consider one another to provoke unto love and to good works." He knew that this also arises from "gathering together." For as "iron sharpeneth iron," so also association increases love. For if a stone rubbed against a stone sends forth fire, how much more soul mingled with soul! But not unto emulation (he says) but "unto the sharpening of love." What is "unto the sharpening of love"? Unto the loving and being loved more. "And of good works"; that so they might acquire zeal. For if doing has greater force for instruction than speaking, ye also have in your number many teachers, who effect this by their deeds.

"But let us consider one another to provoke unto love." What is, "let us consider one another"? For instance if any be virtuous, let us imitate him, let us look on him so as to love and to be loved. For from Love good works proceed. For the assembling is a great good: since it makes love more warm; and out of love all good things arise. For nothing is good which is not done through love.
