John 17:15-21

I do not ask You to take them out of the world, but that You keep them and protect them from the evil one. They are not of the world, just as I am not of the world. Sanctify them in the truth [set them apart for Your purposes, make them holy]; Your word is truth. Just as You commissioned and sent Me into the world, I also have commissioned and sent them (believers) into the world. For their sake I sanctify Myself [to do Your will], so that they also may be sanctified [set apart, dedicated, made holy] in [Your] truth. “I do not pray for these alone [it is not for their sake only that I make this request], but also for [all] those who [will ever] believe and trust in Me through their message, that they all may be one; just as You, Father, are in Me and I in You, that they also may be one in Us, so that the world may believe [without any doubt] that You sent Me.
