XXI. (118) These, then, are the things which, he says, happen in the first instance to others on account of the good man, when they seek to load him with either praise or blame, or with blessings or curses. But that which comes next in order is the most important thing; that when they are silent, still no portion of the rational nature is left without a participation in the benefits; for God says that, “In thee shall all the nations of the world be blessed.” (119) And this is a promise exceedingly full of doctrine; for if the mind is always free from disease and from injury, it then exerts all the tribes of feelings which affect it, and all its powers in a state of sound health, namely, its of seeing and of hearing, and all those which belong to the outward senses; and, moreover, all its appetites which are conversant about pleasures and desires, and all those feelings likewise which being reduced from a state of agitation to one of tranquillity, receive a better character from the change. (120) Before now, indeed, cities, and countries, and peoples, and nations of the earth, have enjoyed the greatest happiness and prosperity in consequence of the virtue and prudence of the individual; especially so when, in addition to a good disposition and wisdom, God has also given him irresistible power, as he may have given to a musician or to any artist the proper instruments for music, or for carrying out any other art, or as wood is supplied as a material for fire; (121) for in good truth the just man is the prop of all the human race; and he, bringing all that he has into a common stock for the advantage of these who can use it, bestows his treasures ungrudgingly, and whatever he finds that he has not got in himself, he prays for to the only giver of all wealth, the all-bounteous God. And God, opening the treasures of heaven, pours forth and showers down upon him all kinds of good things together; so that all the channels on earth are filled with them to overflowing. (122) And these blessings he at all times freely bestows, never rejecting the prayer of supplication which is addressed to him; for it is said in another passage, when Moses addresses him with supplication: “I am favourable to them according to thy Word.”{60}{#nu 14:20.} And this expression, as it seems, is equivalent to the other: “In thee all the nations of the earth shall be blessed.” On which account also the wise Abraham, who had had experience of the goodness of God in all things, believes that even if all other things are destroyed, still a small fragment of virtue would be preserved, like a spark of fire, and that for the sake of this little spark, he pities those other things also, so as to raise them up when fallen, and rekindled them when extinct. (123) For even the slightest spark of fire that is still smouldering, when it is fanned and re-kindled will set fire to a large pile: and so too the smallest spark of virtue, when it beams up, being wakened into life by good hopes, gives light to what has previously been dim-sighted and blind, and causes what has been withered to shoot up again, and whatever is barren and unproductive it transforms and brings to abundance of prolific power. Thus a good, which is but rare, is, by the kindness of God, made abundant and showered upon men, making everything else to resemble itself.
