John 17:20-21 I ask not only on behalf of these, but also on behalf of those who will believe in me through their word, that they all may be one.

Jesus is praying here for his disciples, at the last supper as he prepares to leave them. Then, amazingly, he prays for US: for all those who will come to the faith later on. Jesus asks that he and we and they might all be made one. Hallelujah, we are one.
