Jesus spent His last hours interceding for the disciples and future disciples.  In His last hours, Jesus prayed for Himself and the only thing He wanted was for His Father to be glorified in the work He did for the Father. Jesus desired to be joined and be one with God just as His desire is for us to be joined as one with God.  Though out the ministry of Jesus, He validate His claim as  the Son of God and the gospel God was in Him by the signs and wonders He did so people would believe upon Him to have eternal life.  Jesus gave instructions to the disciple so they would understand and continue in their faith just as we are to continue in our faith. It is the will of the Father for us to continue living our lives by the Spirit rather than in the things of the Evil One. In the prayer of Jesus, it is His desire for us to have the same relationship with the Father as He had with the Father.  It is the prayer and desire of Jesus to show all who believes in Him as the Son of God that we see Him in the glory as the Son of God.
