John 8:24

In the Greek it is only, if ye believe not that I am. Some refer this to Christ's Divine nature; ( I am, is the name of God, Exodus 3:14); but others rather think that Christ here speaketh of himself as the Messiah and Mediator, and so the object of people's faith; and he out of whom there is no salvation: the latter indeed includes the former; for cursed is he that trusteth in man, and maketh flesh his arm, Jeremiah 17:5. The text plainly holds forth an impossibility of salvation for those who, under the revelations of the gospel, receive not and believe not in Christ as Mediator.
