John 6:66-69 - Joseph Benson’s Commentary on the Old and New Testaments

From that time many of his disciples went back This discourse of our Lord was, in all its different branches, so offensive to many, who till now had followed him, and professed to be his disciples, that, from this time, they ceased to attend on or hear him. So that he now began to purge his floor: the proud and careless were driven away, and those only remained who were meet for the Master's use. Then said Jesus unto the twelve Jesus, perceiving this defection to be very general, asked the twelve if they were going to leave him with the rest. Then Peter With his usual zeal; answered, Lord If we were really disposed to quit thee; to whom shall we go? Or, what advantage could we expect by it? Thou hast the words of eternal life Thou, and thou alone, speakest the words which show the way to life everlasting; and hast even now been directing us therein; and God forbid that any other hopes and views should ever be preferred by us to these! And However others may be governed by their carnal prejudices, and a deluded multitude may treat thee with contempt; we firmly believe, and assuredly know, on the most convincing evidence, that thou art the Christ, the Son of the living God On which persuasion we are determined to cleave to thee, to continue to learn of thee as thy disciples, to confide in thee for salvation, present and eternal, and to hazard all in thy service. So that Peter's implicit faith in our Lord's doctrine was founded, as it was right it should be, on his faith in him as the Messiah, the Son of God.
