John 6:68

It is probable that some stayed besides the twelve, for it is said only that many of his disciples turned back. Nor was our Saviour (who knew the hearts of all) ignorant what they would do; but he had a mind both to try them by this question, and also to convince them that there was a false brother amongst them, whose wickedness (though it lay hid from them) would in a short time discover itself.

Jesus said to the twelve: Will you also go away? He shews them, says St. Chrysostom, that he stood not in need of them, and so leaves them to their free choice. (Witham) — Jesus Christ remarking in the previous verse that the apostate disciples had left him, to walk no more with him, turning to the twelve, asks them, Will you also go away? The twelve had heard all that passed; they had seen the Jews strive amongst themselves, and the disciples murmur and leave their Master; they understood what he said in the same literal sense; it could, indeed, bear no other meaning; but when Jesus put the above question to them, leaving them to their free choice, whether to follow him, or to withdraw themselves, Simon Peter answered him: “Lord, to whom shall we go? Thou hast the words of eternal life;” and therefore art able to make good thy words, however hard and difficult they may appear to others. — We may here admire not only the excellency of their faith, but the plain, yet noble motive of their faith: they believe, because he is Christ, the Son of God, (or, as it is in the Greek, the Son of the living God) who is absolutely incapable of deceiving his creatures, and whose power is perfectly equal to perform the promises he here makes them.

2. The believing reply which Peter, in the name of the rest, made to this question, v. 68, 69. Christ put the question to them, as Joshua put Israel to their choice whom they would serve, with design to draw out from them a promise to adhere to him, and it had the like effect. Nay, but we will serve the Lord, Peter was upon all occasions the mouth of the rest, not so much because he had more of his Master's ear than they, but because he had more tongue of his own; and what he said was sometimes approved and sometimes reprimanded (Matt 16 17, 23)—the common lot of those who are swift to speak. This here was well said, admirably well; and probably he said it by the direction, and with the express assent, of his fellow-disciples; at least he knew their mind, and spoke the sense of them all, and did not except Judas, for we must hope the best.

Verses 66-71 When we admit into our minds hard thoughts of the words and works of Jesus, we enter into temptation, which, if the Lord in mercy prevent not, will end in drawing back. The corrupt and wicked heart of man often makes that an occasion for offence, which is matter of the greatest comfort. Our Lord had, in the foregoing discourse, promised eternal life to his followers; the disciples fastened on that plain saying, and resolved to cleave to him, when others fastened on hard sayings, and forsook him. Christ's doctrine is the word of eternal life, therefore we must live and die by it. If we forsake Christ, we forsake our own mercies. They believed that this Jesus was the Messiah promised to their fathers, the Son of the living God. When we are tempted to backslide or turn away, it is good to remember first principles, and to keep to them. And let us ever remember our Lord's searching question; Shall we go away and forsake our Redeemer? To whom can we go? He alone can give salvation by the forgiveness of sins. And this alone brings confidence, comfort, and joy, and bids fear and despondency flee away. It gains the only solid happiness in this world, and opens a way to the happiness of the next.
