John 17:18-21

As You sent Me into the world, I also have sent them into the world. For their sakes I sanctify Myself, that they themselves also may be sanctified in truth. “I do not ask on behalf of these alone, but for those also who believe in Me through their word; that they may all be one; even 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 sent Me.
