John 17:21-23

Young's Literal Translation

²¹ that they all may be one, as Thou Father [art] in me, and I in Thee; that they also in us may be one, that the world may believe that Thou didst send me.

²² `And I, the glory that thou hast given to me, have given to them, that they may be one as we are one;

²³ I in them, and Thou in me, that they may be perfected into one, and that the world may know that Thou didst send me, and didst love them as Thou didst love me.
