John 17:21-23

Amplified Bible

²¹ 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.

Their Future Glory

²² I have given to them the glory and honor which You have given Me, that they may be one, just as We are one; ²³ 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.
