Anyone who thinks himself intelligent because of his scholarly or scientific learning will never be granted insight into divine mysteries unless he first humbles himself and becomes a fool (1 Corinthians 3:18), discarding both his presumption and the knowledge that he has acquired.
But if he does this and with unhesitating faith allows himself to be led by those wise in divine matters, he will enter with them into the city of the living God. Guided and illumined by the divine Spirit, he will see and learn what others cannot ever see or learn. He will then be taught by God (John 6:45).
