In John 17:23 the world beholds the saints' glory as given to Christ, He having given it to them, that it may be known they were loved as He, as a Man, as sent. In verse 24 they behold His as loved before the foundation of the world (this the world does not); therefore they are where He is, “that they may" (which note, for this is a special portion in the glory besides, though connected with communion).
