John 6:67

Again showing that He needeth not their ministry and service, and proving to them that it was not for this that He led them about with Him. For how could He when He used such expressions even to them? But why did He not praise them? why did He not approve them? Both because He preserved the dignity befitting a teacher, and also to show them that they ought rather to be attracted by this mode of dealing. For had He praised them, they might, supposing that they were doing Him a favor, have had some human feeling; but by showing them that He needed not their attendance, He kept them to Him the more. And observe with what prudence He spake. He said not, "Depart ye," (this would have been to thrust them from Him,) but asked them a question, "Will ye also go away?" the expression of one who would remove all force or compulsion, and who wished not that they should be attached to Him through any sense of shame, but with a sense of favor. By not openly accusing, but gently glancing at them, He showeth what is the truly wise course under such circumstances. But we feel differently; with good reason, since we do everything holding fast our own honor, and therefore think that our estate is lowered by the departure of those who attend on us. But He neither flattered nor repulsed them, but asked them a question. Now this was not the act of one despising them, but of one wishing them not to be restrained by force and compulsion: for to remain on such terms is the same as to depart. What then saith Peter?

Our Lord knew well the intentions of the other disciples which stayed, as to staying or going; but yet He put the question to them, in order to prove their faith, and hold it up to imitation: Then said Jesus unto the twelve, Will ye also go away?
