16:7 I go away. Instead of an occasion for sorrow, it was good that the Son should return to the Father. He had assumed a human body, and thus could henceforth be only in one place at a time, like other human beings. In His Spirit, however, He could be with all His disciples in all ages throughout the whole world, for the Spirit is invisible and omnipresent.
16:7 the Comforter. The Comforter is the Holy Spirit (John 14:26), the “Spirit of Truth” (John 15:26), the “paraklete” (Greek—that is, “the one called alongside”). He will come from the Father through the Son (John 15:26), and this He does eternally, for every believer.
