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
Christ wasn't saying that He wasn't equal with the Father, but rather that He was also a man, and therefore in a lower position while in that form.
But we see Jesus, who was made a little lower than the angels for the suffering of death, crowned with glory and honour; that he by the grace of God should taste death for every man.
Hebrews 2:9
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 2:6-8
