John 17:3, 8, 18, 21, 23

And this is eternal life, that they know you, the only true God, and Jesus Christ whom you have sent.

For I have given them the words that you gave me, and they have received them and have come to know in truth that I came from you; and they have believed that you sent me.

As you sent me into the world, so I have sent them into the world.

that they may all be one, just as you, Father, are in me, and I in you, that they also may be in us, so that the world may believe that you have sent me.

I in them and you in me, that they may become perfectly one, so that the world may know that you sent me and loved them even as you loved me.
