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

And this is life eternal, that they should know thee the only true God, and him whom thou didst send, even Jesus Christ.

for the words which thou gavest me I have given unto them; and they received them, and knew of a truth that I came forth from thee, and they believed that thou didst send me.

As thou didst send me into the world, even so sent I them into the world.

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

I in them, and thou in me, that they may be perfected into one; that the world may know that thou didst send me, and lovedst them, even as thou lovedst me.
