6 This man then let us also emulate, and forsaking luxury and drunkenness let us go over unto the life of restraint. For this surely is the time of confession both for the uninitiated and for the baptized; for the one, that upon their repentance they may partake of the sacred mysteries; for the others, that having washed away their stain after baptism, they may approach the table with a clean conscience. Let us then forsake this soft and effeminate way of living. For it is not, it is not possible at once both to do penance and to live in luxury. And this let John teach you by his raiment, by his food, by his abode. What then? Do you require us, you may say, to practise such self-restraint as this? I do not require it, but I advise and recommend it. But if this be not possible to you, let us at least, though in cities, show forth repentance, for the judgment is surely at our doors. But even if it were further off, we ought not even so to be emboldened, for the term of each man's life is the end of the world virtually to him that is summoned. But that it is even at the doors, hear Paul saying, “The night is far spent, the day is at hand;” and again, “He that comes will come, and will not tarry.”
For the signs too are now complete, which announce that day. For “this Gospel of the Kingdoms,” says He, “shall be preached in all the world for a witness unto all nations; and then shall the end come.” Attend with care to what is said. He said not, “when it has been believed by all men,” but “when it has been preached to all.” For this cause he also said, “for a witness to the nations,” to show, that He does not wait for all men to believe, and then for Him to come. Since the phrase, “for a witness,” has this meaning, “for accusation,” “for reproof,” “for condemnation of them that have not believed.”
But we, while hearing these things and seeing them, slumber, and see dreams, sunk in a lethargy, as in some very deepest night. For the things present are nothing better than dreams, whether they be prosperous, or whether they be painful. Wherefore I entreat you now at length to be awakened, and to look another way, unto the Sun of Righteousness. For no man while sleeping can see the sun, nor delight his eyes with the beauty of its beams; but whatever he may see, he beholds all as in a dream. For this cause we need much penance, and many tears; both as being in a state of insensibility while we err, and because our sins are great, and beyond excuse. And that I lie not, the more part of them that hear me are witnesses. Nevertheless, although they be beyond excuse, let us repent, and we shall receive crowns.
