I have given them the glory that you gave me, that they may be one as we are one — I in them and you in me—so that they may be brought to complete unity. Then the world will know that you sent me and have loved them even as you have loved me. (John 17:22-23 NIV)
In John 17, Jesus is praying to his Father and giving an account of the things he has accomplished during his time on earth. It reads like the completion, or fulfilment, of a mission statement: "This is what you sent me to do and this is what I have done".
The prayer contains an important list of things the Son has done is making his Father known.
"That they may be one, as we are one". The life that is in Jesus is in us. The relationship Jesus has with his Father is imparted to us, we can have the same intimate relationship, with the Father, that Jesus had.
When Jesus prays that we may be one, we often think that he is talking about our relationships with one another. I believe that is correct. But as I've meditated on this verse, I wonder if there is another interpretation or meaning to Jesus' words. What about us being one with him in the same way that Jesus is one with him?
Having prayed that we may be one he then expresses his desire for us to be involved, or to live in, the unity of the Trinity. He really wants us to know that we are in him as much as he is in us. It is a profound description of unity and intimacy. This is not a distant relationship, but the closest of Father-Son relationships and we are invited to participate.
As Jesus accounts to his Father for the things he has accomplished, he is clear that we have been enabled to live like the Trinity live. A life of intimacy and unity is one of rest and peace. It is a fulfilled life.
