3 Endure thou the night, yearn for the morning. Think not because the night has life, the morning too has not life. Does then he that sleeps live, and he that rises live not? Is not he that sleeps more like death? And who are they that sleep? They whom the Apostle Paul rouses, if they choose but to awake. For to certain he says, “Awake, you that sleepest, and arise from the dead, and Christ shall give you light.” They then that are lightened by Christ watch now, but the fruit of their watchings appears not yet: in the morning it shall appear, that is, when doubtful things of this world shall have passed away. For these are very night: for do they not appear to you like darkness?...But they on whom men have trampled, and who were ridiculed for believing, shall hear from Life Itself, whom they have for shepherd, “Come, you blessed of My Father, receive the kingdom which was prepared for you from the foundation of the world.” Therefore the righteous “shall reign over them,” not now, but “in the morning.” Let no one say, Wherefore am I a Christian? I rule no one, I would rule the wicked. Be not in haste, you shall reign, but “in the morning.” “And the help of them shall grow old in hell from their glory.” Now they have glory, in hell they shall grow old. What is “the help of them”? Help from money, help from friends, help from their own might. But when a man shall be dead, “in that day shall perish all his thoughts.” How great glory he seemed to have among men, while he lived, so great oldness and decay of punishments shall he have, when he shall be dead in hell.
4. “Nevertheless, God shall redeem my soul”. Behold the voice of one hoping in the future: “Nevertheless, God shall redeem my soul.” Perhaps it is the voice of one still wishing to be relieved from oppression. Some one is in prison, he says, “God shall redeem my soul:” some one is in bond, “God shall redeem my soul:” some one is suffering peril by sea, is being tossed by waves and raging tempests, what says he? “God shall redeem my soul.” They would be delivered for the sake of this life. Not such is the voice of this man. Hear what follows: “God shall redeem my soul from the hand of hell, when He shall have received me.” He is speaking of this redemption, which Christ now shows in Himself. For He has descended into hell, and has ascended into heaven. What we have seen in the Head we have found in the Body. For what we have believed in the Head, they that have seen, have themselves told us, and by themselves we have seen: “For we are” all “one body.” But are they better that hear, we worse to whom it has been told? Not so says The Life Itself, Our Shepherd Himself. For He rebukes a certain disciple of His, doubting and desiring to handle His scars, and when he had handled the scars and had cried out, saying, “My Lord and my God,” seeing His disciple doubting, and looking to the whole world about to believe, “Because you have seen Me,” He says, “you have believed: blessed are they that see not, and believe.” “But God shall redeem my soul from the land of hell, when He has received me.” Here then what? Labour, oppression, tribulation, temptation: expect nothing else. Where joy? In future hope....
5....Perchance your heart says, Wretch that I am, I suppose to no purpose I have believed, God does not regard things human. God therefore does awaken us: and He says what? “Fear not, though a man have become rich”. For why did you fear, because a man has become rich? You feared that you had believed to no purpose, that perchance you should have lost the labour for your faith, and the hope of your conversion: because perchance there has come in your way gain with guilt, and you could have been rich, if you had seized upon that same gain with the guilt, and needed not have laboured; and you, remembering what God has threatened, have refrained from guilt, and have contemned the gain: you see another man that has made gain by guilt, and has suffered no harm; and you fear to be good. “Fear not,” says the Spirit of God to you, “though a man shall have become rich.” Would you not have eyes but for things present? Things future He has promised, who has risen again; peace in this world, and repose in this life, He has not promised. Every man does seek repose; a good thing he is seeking, but not in the proper region thereof he is seeking it. There is no peace in this life; in Heaven has been promised that which on earth we are seeking: in the world to come has been promised that which in this world we are seeking.
