Jesus had glorified the Father by all that He had done in His incarnation. Jesus probably intended to include His death, resurrection, and ascension, to which He referred proleptically here (cf. John 19:30). Jesus" crucifixion was a foregone certainty because of His commitment to do the Father"s will ( Philippians 2:8). Now He asked the Father to glorify the Son by all that the Father would do in exalting the Son. Thus Jesus essentially restated the request of John 17:1. He wanted to return to the condition in which He existed with His Father before His incarnation. This request presupposes Jesus" preexistence with the Father and His equality with the Father ( John 10:30). Really Jesus requested His own glorification. [source][source][source]
