13. Those who say these things do not yet understand thee, O Wisdom of God, O Light of souls. They do not yet understand how the things are made that are made by and in thee. They endeavor to comprehend eternal things, but their heart still flies about in the past and future motions of created things, and is still unstable. Who shall hold it and fix it so that it may come to rest for a little; and then, by degrees, glimpse the glory of that eternity which abides forever; and then, comparing eternity with the temporal process in which nothing abides, they may see that they are incommensurable? They would see that a long time does not become long, except from the many separate events that occur in its passage, which cannot be simultaneous. In the Eternal, on the other hand, nothing passes away, but the whole is simultaneously present. But no temporal process is wholly simultaneous. Therefore, let it see that all time past is forced to move on by the incoming future; that all the future follows from the past; and that all, past and future, is created and issues out of that which is forever present. Who will hold the heart of man that it may stand still and see how the eternity which always stands still is itself neither future nor past but expresses itself in the times that are future and past? Can my hand do this, or can the hand of my mouth bring about so difficult a thing even by persuasion?
