Who this Comforter is, our blessed Saviour had before declared, chap. xv. 26. He is Πνεῦμα τῆς ἀληθείας, “the Spirit of truth;” that is, the Holy Ghost, who revealeth all truth to the sons of men. Now, of this Comforter two things are affirmed:— (1.) That he shall come. (2.) That Christ shall send him.
