Shall a trumpet be blown in the city, and the people not be afraid? shall there be evil in a city, and the LORD hath not done it? (Prophet Amos 3:6)
St John Chrysostom ― Homily One Concerning the Power of Demons:
Whenever therefore thou seest that famines have taken place, and pestilences, and drought and immoderate rains, and irregularities in the atmosphere, or any other of the things which chasten human nature, be not distressed, nor be despondent, but worship Him who caused them, marvel at Him for His tender care. For He who does these things is such that He even chastens the body that the soul may become sound. Then does God these things saith one? God does these things, and even if the whole city, nay even if the whole universe were here I will not shrink from saying this. Would that my voice were clearer than a trumpet, and that it were possible to stand in a lofty place, and to cry aloud to all men, and to testify that God does these things. I do not say these things in arrogance but I have the prophet standing at my side, crying and saying, "There is no evil in the city which the Lord hath not done"--now evil is an ambiguous term; and I wish that you shall learn the exact meaning of each expression, in order that on account of ambiguity you may not confound the nature of the things, and fall into blasphemy.
