9 It was in thought of this that the spirit of the Prophet added the words, “which do His word.” Think not then that these things are moved by chance, which in every motion of theirs obey God. Whither God wills, there the fire spreads, there the cloud hurries, whether it carry in it rain, or snow, or hail. And wherefore does the lightning sometimes strike the mountain, yet strikes not the robber?...Perhaps He yet seeks the robber's conversion, and therefore is the mountain which fears not smitten, that the man who fears may be changed.
Thou also sometimes, when maintaining discipline, smitest the ground to terrify a child. Sometimes too He smites a man, whom He will. But you say to me, Behold, He smites the more innocent, and passes over the more guilty. Wonder not; death, whencesoever it come, is good to the good man. And whence do you know what punishment is reserved in secret for that more guilty man, if he be unwilling to be converted? Would not they rather be scorched by lightning, to whom it shall be said in the end, “Depart into everlasting fire”? The needful thing is, that you be guileless.
Why so? Is it an evil thing to die by shipwreck, and a good thing to die by fever? Whether he die in this way or in that, ask what sort of man he is who dies; ask whither he will go after death, not how he is to depart from life....Whatever then happens here contrary to our wish, you will know that it happens not, save by the will of God, by His providence, by His ordering, by His nod, by His laws: and if we understand not why anything is done, let us grant to His providence that it is not done without reason: so shall we not be blasphemers.
For when we begin to argue concerning the works of God, “why is this?” “why is that?” and, “He ought not to have done this,” “He did this ill;” where is the praise of God? You have lost your Halleluia. Regard all things in such wise as to please God and praise the Creator. For if you were to happen to enter the workshop of a smith, you would not dare to find fault with his bellows, his anvils, his hammers. But take an ignorant man, who knows not for what purpose each thing is, and he finds fault with all.
But if he have not the skill of the workman, and have but the reasoning power of a man, what says he to himself? Not without reason are the bellows placed here: the workman knows wherefore, though I know not. In the shop he dares not to find fault with the smith, yet in the universe he dares to find fault with God. Therefore just as “fire, hail, snow, ice, wind of storms, which do His word,” so all things in nature, which seem to foolish persons to be made at random, simply “do His word,” because they are not made save by His command.
