Christ encourages the beginnings of faith in the souls of his people, and magnifies Nathanael's faith from the revelation which he had, which was but imperfect; for Christ had said no more, than that he had seen him under the fig tree before Philip called him. He tells him that he should see greater things than these. To him that hath, shall be given. What those greater things are, which our Lord here meaneth, he telleth him, in part at least, 1 Thessalonians 1:51.
