23 Look, therefore, while there is time, to the true and eternal salvation; and since now the end of the world is at hand, turn your minds to God, in the fear of God; nor let that powerless and vain dominion in the world over the just and meek delight you, since in the field, even among the cultivated and fruitful grain, the tares and the darnel have dominion. Nor say that ill fortunes happen because your gods are not worshipped by us; but know that this is the judgment of God's anger, that He who is not acknowledged on account of His benefits may at least be acknowledged through His judgments.
Seek the Lord even late; for long ago, God, forewarning by His prophet, exhorts and says, “Seek the Lord, and your soul shall live.” Know God even late; for Christ at His coming admonishes and teaches this, saying, “This is life eternal, that they might know You, the only true God, and Jesus Christ, whom You have sent.” Believe Him who deceives not at all. Believe Him who foretold that all these things should come to pass. Believe Him who willgive to all that believe the reward of eternal life. Believe Him who will call down on them that believe not, eternal punishments in the fires of Gehenna.
