“Ye have heard how I said unto you, I go away, and come again unto you. If ye loved me, ye would rejoice, because I said, I go unto the Father: for my Father is greater than I.” John 14:28 (KJV 1900)
“Let this mind be in you, which was also in Christ Jesus: Who, being in the form of God, thought it not robbery to be equal with God: But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men: And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross.” Philippians 2:5–8 (KJV 1900)
My position is that Jesus did not stop being God, but made himself of no reputation as God, while making himself of great reputation as man. And so people naturally see the manhood of Jesus in scripture before they see his divinity. The manhood needs no special revelation, but his Messiahship does. As in the case of Peter to whom God revealed Christ's divinity (Messiahship).
“And now, O Father, glorify thou me with thine own self with the glory which I had with thee before the world was.” John 17:5 (KJV 1900)
Going to his Father who is greater means Jesus returns to his former greatness.
God is not greater than the father in essence, only in incarnation.
here is a commentary on it:
2. (
Jhn 14:28-29) The goodness of Jesus’ departure to the Father.
“You have heard Me say to you, ‘I am going away and coming
back to you.’ If you loved Me, you would rejoice because I said, ‘I am going to the Father,’ for My Father is greater than I. And now I have told you before it comes, that when it does come to pass, you may believe.”
a.
If you loved Me, you would rejoice: The disciples were troubled at the news of Jesus’ departure. In faith, they should instead
rejoice, for the sake of Jesus, for their own sake, and for the sake of the world. The work of Jesus through the sent Holy Spirit would be greater than His work during the years of His earthly ministry.
· Jesus, when I think of all You gave up, all You took upon Yourself when You came from heaven to earth – it makes me happy that You are
going to the Father to have it all restored to You
· Jesus, when I think of all You will give to me and all Your people when You ascend to glory and from there send forth the Holy Spirit, pray for Your church, and prepare a place for us – it makes me happy that You are
going to the Father, also for my sake
b.
Because I said, “I am going to the Father”: We sense a joyful anticipation in Jesus, happy in His soon return to heaven’s fellowship between Father and Son.
c.
My Father is greater than I: The Father
is greater than the Son in
position, especially in regard to the incarnation. Yet the Father is
notgreater than the Son in
essence or
being; They are both equally God.
i. It is remarkable that Jesus should even say this. “That it should require to be explicitly affirmed, as here, is strongest evidence that He was Divine.” (Dods)
