I came from the Father and have come into the world. Again I am leaving the world and am going to the Father."

I came out from the Father and have come into the world: again, I go away from the world and go to the Father.

I went forth from the Father, and I have come into the world. Next I am leaving the world, and I am going to the Father."

I came out from the Father. This mode of expression draws our attention to the Divine power which is in Christ. Our faith in him would not be steady, if it did not perceive his Divine power; for his death and resurrection, the two pillars of faith, would be of little avail to us, if heavenly power were not connected with them. We now understand in what manner we ought to love Christ. Our love ought to be of such a nature that our faith shall contemplate the purpose and power of God, by whose hand he is offered to us. for we must not receive coldly the statement that he came out from God, but must also understand for what reason and for what purpose he came out, namely, that he might be to us wisdom, and righteousness, and sanctification, and redemption, (1-Corinthians 1:30.) Again, I leave the world, and go to the Father. By this second clause he points out to us that this power is perpetual- for the disciples might have thought that it was a temporary blessing, that he was sent into the world to be a Redeemer. He therefore said that he returns to the Father, that they may be fully persuaded that none of those blessings which he brought are lost by his departure, because from his heavenly glory he sheds on the world the power and efficacy of his death and resurrection. He therefore left the world when, laying aside our weaknesses, he was received into heaven; but his grace toward us is still in all its force, because he is seated at the right hand of the Father, that he may sway the scepter of the whole world.

1 - "A fin d'estre Empereur et Dominateur de tout le monde;" -- "in order to be the Emperor and Ruler of the whole world."

I came forth from the Father - I came sent by the Father.
And am come into the world - See John 3:19; John 6:14, John 6:62; John 9:39.

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.

I came forth from the Father,.... This is the sum of what the apostle believed, and Christ, in these discourses of his, had been speaking of. This his coming forth from the Father is to be understood, not of his eternal filiation; nor of his coming forth in a way of grace towards his own people in the council and covenant of grace and peace; nor of his constitution, as Mediator, from everlasting; but of his coming in the flesh in the fulness of time: which supposes that he was, that he existed as a divine person before; that he was with the Father before; that he came forth from him with his knowledge, mind, and will; he came not of himself, but he sent him; and yet he came willingly, was not forced, or did not come against his will: and this does not suppose any local motion, or change of place, but only intends an assumption of the human nature into unity with his divine person, who fills heaven and earth with his presence; nor any separation from his Father, with whom he was, and in whose bosom he lay when he was made flesh, and dwelt among men; nor any absence from heaven, for he was there when on earth.
And am come into the world; where he was before, as the Creator and upholder of it, by his immensity and powerful presence; this designs his coming and manifestation in the flesh, which in general was to do the whole will of God, which he in council and covenant agreed to do, and for which he came down from heaven; and in particular to preach the Gospel, call sinners to repentance, give life and light to many, and to fulfil the law, by obeying its precepts, and bearing its penalty, and both to do and suffer in the room and stead of his people, and to save lost sinners, even the chief of them.
Again, I leave the world; not that he relinquished the sustaining and government of it, as God, nor the care of his people in it, as Mediator, for whom he retains the same love as ever, and will not leave them fatherless and comfortless; nor was he leaving it as never to return more; for he will descend, in like manner he ascended, and will come a second time and judge the world in righteousness: but he was about to depart from it by death, having done the work and business for which he came about.
And go to the Father; to give an account of his work unto him, as his righteous servant, being faithful to him that had appointed him; and to transact the affairs of his people; to appear in the presence of God for them; to present their petitions, be their advocate, make intercession for them, take possession of heaven in their name, and prepare it for them; to take his place at the right hand of God in human nature, and to be glorified with the glory promised him before the world was.

Here is a plain declaration of Christ's coming from the Father, and his return to him. The Redeemer, in his entrance, was God manifest in the flesh, and in his departure was received up into glory. By this saying the disciples improved in knowledge. Also in faith; "Now are we sure." Alas! they knew not their own weakness. The Divine nature did not desert the human nature, but supported it, and put comfort and value into Christ's sufferings. And while we have God's favourable presence, we are happy, and ought to be easy, though all the world forsake us. Peace in Christ is the only true peace, in him alone believers have it. Through him we have peace with God, and so in him we have peace in our own minds. We ought to be encouraged, because Christ has overcome the world before us. But while we think we stand, let us take heed lest we fall. We know not how we should act if brought into temptation; let us watch and pray without ceasing, that we may not be left to ourselves.

I came forth from the Father, &c.--that is, "And ye are right, for I have indeed so come forth,and shall soon return whence I came." This echo of the truth, alluded to in John 16:27, seems like thinking aloud, as if it were grateful to His own spirit on such a subject and at such an hour.
