Isaías 45

Isaías 45:3

Who is the person whose heart has never been made to burn, as the Scriptures have been opened, with the pure words of God that have been tried in a furnace;16 who has not, by a triple inscription of them on the breadth of his heart, attained the mind of Christ, or been admitted to the treasures that to most people remain hidden, secret and dark, to gaze on the riches therein and become able to enrich others, comparing spiritual things with spiritual. — IN DEFENSE OF HIS FLIGHT TO PONTUS, ORATION 2:96
