"For God 'subjected all things under his feet.' (Ps 8:6) But when he says that 'all things have been subjected,' (Heb 2:8) it is evident that this does not include the One who subjected all things to him. (1Pe 3:22) But when all things will have been subjected to him, then the Son himself will also subject himself to the One who subjected all things to him, (Joh 14:28) that God may be all things to everyone. (1Co 3:23) - 1 Corinthians 15:28,29
Jesus, after bringing all creation back into harmony with God's will, then returns the authority given to him by God. How can he be both the authority giver and the authority receiver? Does not the idea that God is Jesus create a lot of confusion when reading verses like this?
Nope. Jesus is of the same essence/nature as the Father. He differs only in rank or position as the second person of the Trinity. As such (son) he will be subject to his father just as Jesus was subject to his mother and father in his human nature while on earth.
Then he (Jesus) went down to Nazareth with them (Joseph and Mary) and was obedient to them. Luke 2:51
