John 17:17-23

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. I have given to them the glory and honor which You have given Me, that they may be one, just as We are one; I in them and You in Me, that they may be perfected and completed into one, so that the world may know [without any doubt] that You sent Me, and [that You] have loved them, just as You have loved Me.
