John 17:20-26

In chapter 17, Jesus has prayed for himself and for his disciples.  In this passage, he prays for all of those who would believe in himthroughout the ages, including us. The unity that believers have with each other is to be so profound that it mimics the unity that God the Father has with God the Son.  It is based upon a common belief, and it results in love for one another  and a common purpose in glorifying God.  This unity is to be so  uncommonly unusual and powerful that it causes non-Christians to  desire to know Christ. Jesus then prays that believers will be able to see the glory of God.  As they see this glory, they will be changed by it, so that they will know God fully and love each other fully.
