Then said Jesus unto them,
When you have lifted up the Son of man, then shall you know that I am he, and that I do nothing of myself; but as my Father has taught me, I speak these things.

Then said Jesus, &c. When ye have lifted Me up on the Cross. He calls it His exaltation, for though it seemed to be His greatest degradation and disgrace, yet it was made to be, by God"s Providence, His greatest exaltation and glory, that all nations should adore Christ crucified, and hope for pardon from Him. For this Christ won for Himself by His great humility (see Philippians 2:8 seq.). And thus does God deal with every follower of Christ who humbles himself for Christ"s sake, as He says, "Every one that exalteth himself shall be humbled," &c.
Then shall you know that I am Messiah, the Son of God, whom I declare Myself to be, and not a mere Prayer of Manasseh , as ye now think Me. For many of the Jews, when they saw in the Cross, Death, and Resurrection of Jesus Christ, such patience, charity, zeal, and such great prodigies and miracles, were moved with compunction to believe in Him. Christ had obtained all this by His Cross, and obtained it from His Father (see Acts 2:41). As S. Augustine says, "He saw that many would believe after His Passion. And this He says that no one who is conscious of guilt should despair, when even His own murder was condoned." See S. Cyril, and others.
I do nothing of Myself, &c. Christ frequently inculcates the same truth, both in order to speak humbly of Himself, and to gain authority for His doctrine from God the Father. "But the Father," says S. Augustine, "did not so teach the Song of Solomon , as though He were ignorant when He begat Him; but His teaching Him, was His begetting Him full of knowledge." For with the Son His being is His knowledge. And therefore the Father by begetting gave Him both existence and knowledge.
