John 17:21-23
17:21 that they will all be one, just as you, Father, are in me and I am in you. I pray that they will be in us, so that the world will believe that you sent me.
17:22 The glory you gave to me I have given to them, that they may be one just as we are one –
17:23 I in them and you in me – that they may be completely one, so that the world will know that you sent me, and you have loved them just as you have loved me.
