Note, in John 14, verse 3 gives Christ as going away and coming again, the position of the disciples as to His personal presence. Then comes what they ought to have known by the presence of the Lord Jesus as an abiding truth, whether He were on earth or in heaven; the revelation of the Father by the Son; that He was in the Father, and the Father in Him;
the coming of the Comforter involved; and the truth, not that the Father was in Him that was manifested on earth, but that He was in the Father (being on high), and that they were in Him, and He in them. The union and reciprocal indwelling was first of the Father and the Son; then (the divine union of the Son with the Father being repeated, He being in the Father, which was divine, and the natural point as their Head) the union, and reciprocal union, of the disciples and the Son was next stated, the knowledge of which depended on the presence of the Comforter, on His going away, which note.
