Gregory the Great

And again speaking by the comparison of a wife, He says: "Even if she shall have forgotten, yet will I not forget thee." For who can be ignorant, that the memory of God is neither broken off by oblivion, nor yet repaired by recollection? But when He neglects and passes over some things, He is said, after the manner of minds, to forget, and when, after a long time, He visits the things He wills, He is said, after the fashion of our changeableness, to have remembered. For how does oblivion weaken the strength of that Godhead, with Which even praiseworthy memory itself has no essential agreement. For men remember no things, except those which are either past or absent. How then does God remember past things, when the very things which in themselves pass away, stand ever present at His beck? Or how does He call to mind things absent, when every thing that is, is present to Him, from the fact that it exists in Him? For if it were not present to Him, it would not exist at all; for things nonexistent He creates, by looking on them, things existent He keeps together, by looking on them.
