But I have greater witness— Our Lord told them that he had the testimony of one infinitely greater than John: even the testimony of the Father, who was continually bearing witness to him by the miracles which he empowered him to perform, and who had given him a peculiar and direct testimony at his baptism, by declaring from heaven in a grand, audible, articulate voice, that he was his Beloved Son; which voice many then living had heard, and no doubt remembered. See the beginning of John 5:37 and the note on ch. John 3:2.
