7 Nor let it disturb you, dearest brethren, if with some, in these last times, either an uncertain faith is wavering, or a fear of God without religion is vacillating, or a peaceable concord does not continue. These things have been foretold as about to happen in the end of the world; and it was predicted by the voice of the Lord, and by the testimony of the apostles, that now that the world is failing, and the Antichrist is drawing near, everything good shall fail, but evil and adverse things shall prosper.
