And now, O Father, glorify thou me with thine own self with the glory which I had with thee before the world was.
The verse is plain enough and in context with the message John is conveying. Jesus was asking His Father to restore him to the glory (the non-human nature) the Word had as creator. In this glory our Lord could then raise his executed human body as prophesied thus becoming the only Being to possess a dual nature. This dual or hypostasis nature can now be used to further the Kingdom interest and was used to do this very thing for the 40 days our Lord continued here on earth. Such use does not change history or the value of the that sacrifice and was actually authorize by God like this:
Joh 10:18 No man taketh it from me, but I lay it down of myself. I have power to lay it down, and I have power to take it again. This commandment have I received of my Father.
This authorization will continue when our Lord returns once again in the flesh to rule in this Kingdom here on earth as promised. When this presence begins our Lord will be here literally and visibly not in some invisible form existing somewhere else as most teach.
