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

And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.

For I have given unto them the words which thou gavest me; and they have received them, and have known surely that I came out from thee, and they have believed that thou didst send me.

As thou hast sent me into the world, even so have I also sent them into the world.

that they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me.

I in them, and thou in me, that they may be made perfect in one; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me.
