In John 14:28 Jesus said “You heard me say to you, ‘I am going away, and I will come to you.’ If you loved me, you would have rejoiced, because I am going to the Father, for the Father is greater than I.” Since the Father is greater than Jesus, doesn’t that mean that Jesus is not God?

No. We read in John 1:1 that in the beginning Jesus was with God and Jesus was God. There is also John 10:30 where Jesus said, “I and the Father are one.” We can see from scripture that although Jesus is God, just as the Father is God, the Father holds a higher ‘office’ than the Son. This does not mean that the Father is God and the other persons of the Trinity are not. Just as an earthly father is equally human with, but holds a higher office than his son, even so the Father and the Son in the Trinity are equal in essence, but different in function. In like manner, we speak of the president of our country as being a greater man, not by virtue of his character, but by virtue of his position. Therefore, Jesus cannot ever be said to say that He considered Himself anything less than God by nature. The following summary helps to crystalize the differences:
