I came forth from the Father, and am come into the world: again, I leave the world, and go to the Father. I came forth from the Father - With whom I existed from eternity in glory.
Am come into the world - By my incarnation.
I leave the world - By my death.
And go to the Father - By my ascension. These four words contain the whole economy of the Gospel of man's salvation, and a consummate abridgment of the Christian faith. This gave the disciples a key to the whole of our Lord's discourse; and especially to that part, John 16:16, that had so exceedingly embarrassed them, as appears by John 16:17, John 16:18.
