The soul, then, shall have an intellectual remembrance of its past ills; but, so far as regards sensible experience, they shall be quite forgotten. For a skilful physician knows, indeed, professionally almost all diseases; but experimentally he is ignorant of a great number which he himself has never suffered from. As, therefore, there are two ways of knowing evil things,—one by mental insight, the other by sensible experience, for it is one thing to understand all vices by the wisdom of a cultivated mind, another to understand them by the foolishness of an abandoned life,—so also there are two ways of forgetting evils. For a well-instructed and learned man forgets them one way, and he who has experimentally suffered from them forgets them another,—the former by neglecting what he has learned, the latter by escaping what he has suffered. And in this latter way the saints shall forget their past ills, for they shall have so thoroughly escaped them all, that they shall be quite blotted out of their experience. But their intellectual knowledge, which shall be great, shall keep them acquainted not only with their own past woes, but with the eternal sufferings of the lost. For if they were not to know that they had been miserable, how could they, as the Psalmist says, for ever sing the mercies of God? Certainly that city shall have no greater joy than the celebration of the grace of Christ, who redeemed us by His blood. There shall be accomplished the words of the psalm, "Be still, and know that I am God." There shall be the great Sabbath which has no evening, which God celebrated among His first works, as it is written, "And God rested on the seventh day from all His works which He had made. And God blessed the seventh day, and sanctified it; because that in it He had rested from all His work which God began to make." For we shall ourselves be the seventh day, when we shall be filled and replenished with God's blessing and sanctification. There shall we be still, and know that He is God; that He is that which we ourselves aspired to be when we fell away from Him, and listened to the voice of the seducer, "Ye shall be as gods," and so abandoned God, who would have made us as gods, not by deserting Him, but by participating in Him. For without Him what have we accomplished, save to perish in His anger? But when we are restored by Him, and perfected with greater grace, we shall have eternal leisure to see that He is God, for we shall be full of Him when He shall be all in all. For even our good works, when they are understood to be rather His than ours, are imputed to us that we may enjoy this Sabbath rest. For if we attribute them to ourselves, they shall be servile; for it is said of the Sabbath, "Ye shall do no servile work in it." Wherefore also it is said by Ezekiel the prophet, "And I gave them my Sabbaths to be a sign between me and them, that they might know that I am the Lord who sanctify them." This knowledge shall be perfected when we shall be perfectly at rest, and shall perfectly know that He is God.
