John 17:21-23

21 I pray that they may all be one. Father! May they be in us, just as you are in me and I am in you. May they be one, so that the world will believe that you sent me.
22 I gave them the same glory you gave me, so that they may be one, just as you and I are one:
23 I in them and you in me, so that they may be completely one, in order that the world may know that you sent me and that you love them as you love me.
