The Confessions: Chapter XIX

Chapter XIX.—We are Ignorant in What Manner God Teaches Future Things.

25. Thou, therefore, Ruler of Thy creatures, what is the method by which Thou teachest souls those things which are future? For Thou hast taught Thy prophets. What is that way by which Thou, to whom nothing is future, dost teach future things; or rather of future things dost teach present? For what is not, of a certainty cannot be taught. Too far is this way from my view; it is too mighty for me, I cannot attain unto it; 1042 but by Thee I shall be enabled, when Thou shalt have granted it, sweet light of my hidden eyes.
