21 Let no one, however, flatter himself, because there is for the present to us and to the profane, to God's worshippers and to God's opponents, by reason of the equality of the flesh and body, a common condition of worldly troubles, in such a way as to think from this, that all those things which happen are not drawn down by you; since by the announcement of God Himself, and by prophetic testimony, it has previously been foretold that upon the unjust should come the wrath of God, and that persecutions which humanly would hurt us should not be wanting; but, moreover, that vengeance, which should defend with heavenly defence those who were hurt, should attend them.
