YOU fail to understand that the EXPRESS IMAGE OF GOD, a creation, was given the fullness of the Father. He was second only to his Father (creator). God created everything through his Spirit SON Christ. No one has the power and glory that the Father has, for he is the most high God.
Joh_17:5 And now, O Father, glorify thou me with thine own self with the glory which I had with thee before the world was.
He says here that He had glory before but he does not say he has his Father's glory.
Here it is in the Aramaic Translation:
Yochanan 17:5
5. And now glorify me my Father with You in that glory that I had with You from before the world was.
