28 I came from the Father and have come into the world; again I leave the world and I am going to the Father.”
29 His disciples said: “See, now You speak plainly, no longer speaking figuratively.
30 Now we know that You know all things and that You have no need that anyone should question You. By this we believe that You came from God.”
Jesus plainly tells the disciples that He had come out from the Father. This is considerably different from saying that He had been sent by the Father. To come out from means that He must have been with the Father in order to come out from Him.
The prophets of the Old Testament had been sent by God, but they were not with God. Therefore, they did not come out from Him.
Isaiah gave this testimony:
Then I heard the Lord asking, “Whom should I send as a messenger to My people? Who will go for us?”
And I said, “Lord, I’ll go! Send me” – Isaiah 6.8 (NLT).
He responded to what the Lord was saying and submitted himself to be God’s prophetic messenger. From this God sent Him to bring His word to the world.
With Jesus it was different. He was with God and was God (John 1.1).
What Jesus said to His disciples was another claim to His eternal existence, and His being one with the Father.
By saying that He had come into the world He was saying more than that He was born. We are all conceived and born into the world. However, Jesus was conceived by means of the Holy Spirit overshadowing Mary, and not by the seed of Joseph.
These words of Jesus are in total agreement with what Jesus had prayed a little earlier:
And now, Father, glorify Me with the glory We had together before the beginning of the world – John 17.5.
Jesus went on to say that He was to leave this world and return to the Father.
His return to the Father and to glory, was to be by the means of the cross. His return to glory was to be by means of human humiliation as He was nailed to the cross; facing the scorn and abuse of those He came to save.
Herein is the foundation of our salvation: Jesus came from the Father, paid the price of our sin by being the one, eternal sacrifice for us, and by returning to the Father, leading us in triumph with Him.
