They Who Ask This Have Not as Yet Known the Eternity of God, Which is Exempt from the Relation of Time
13 Those who say these things do not as yet understand You, O Thou Wisdom of God, Thou light of souls; not as yet do they understand how these things be made which are made by and in You. They even endeavour to comprehend things eternal; but as yet their heart flies about in the past and future motions of things, and is still wavering. Who shall hold it and fix it, that it may rest a little, and by degrees catch the glory of that everstanding eternity, and compare it with the times which never stand, and see that it is incomparable; and that a long time cannot become long, save from the many motions that pass by, which cannot at the same instant be prolonged; but that in the Eternal nothing passes away, but that the whole is present; but no time is wholly present; and let him see that all time past is forced on by the future, and that all the future follows from the past, and that all, both past and future, is created and issues from that which is always present?
Who will hold the heart of man, that it may stand still, and see how the still-standing eternity, itself neither future nor past, utters the times future and past? Can my hand accomplish this, or the hand of my mouth by persuasion bring about a thing so great?
