At last the assembly is dissolved, the spectacle of this life ceases: its deceit and its semblance are passed away. Cleave to me, to whom every knee bows, of things in heaven, and things on earth, and things under the earth. For all who have been negligent, and have not shown pity in well-doing there, have nothing else due them than the unquenchable fire. For I am the friend of man, but yet also a righteous Judge to all. For I shall award the recompense according to desert; I shall give the reward to all, according to each man's labour; I shall make return to all, according to each man's conflict. I wish to have pity, but I see no oil in your vessels. I desire to have mercy, but you have passed through life entirely without mercy. I long to have compassion, but your lamps are dark by reason of your hardness of heart. Depart from me. For judgment is without mercy to him that has showed no mercy.
