6 Therefore also here: “My time is not yet come; but your time,” that is the glory of the world, “is always ready.” This is the time of which Christ, that is the body of Christ, speaks in prophecy: “When I shall have received the fit time, I will judge righteously.” For at present it is not the time of judging, but of tolerating the wicked. Therefore, let the body of Christ bear at present, and tolerate the wickedness of evil livers. Let it, however, have righteousness now, for by righteousness it shall come to judgment.
And what says the Holy Scripture in the psalm to the members—namely, that tolerate the wickedness of this world? “The Lord will not cast off His people.” For, in fact, His people labors among the unworthy, among the unrighteous, among blasphemers, among murmurers, detractors, persecutors, and, if they are allowed, destroyers. Yes, it labors; but “the Lord will not cast off His people, and He will not forsake His inheritance until justice is turned into judgment.” “Until the justice,” which is now in His saints, “be turned into judgment;” when that shall be fulfilled which was said to them, “You shall sit upon twelve thrones, judging the twelve tribes of Israel.” The apostle had righteousness, but not yet that judgment of which he says, “Do you not know that we shall judge angels?” Be it now, therefore, the time for living rightly; the time for judging them that have lived ill shall be hereafter.
“Until righteousness,” says he, “is turned into judgment.” The time of judgment will be that of which the Lord has here said, “My time is not yet come.” For there will be a time of glory, when He who came in humility will come in loftiness; He who came to be judged will come to judge; He who came to be slain by the dead will come to judge the quick and the dead. “God,” says the psalm, “will come manifest, our God, and He will not be silent.” What is “shall come manifest”? Because He came concealed. Then He will not be silent; for when He came concealed, “He was led as a sheep to the slaughter; and as a lamb before its shearer, He opened not His mouth.” He shall come, and shall not keep silence. “I was silent,” says He, “shall I always be silent?”
