He here calleth the salvation of men “meat,” showing what an earnest desire He hath of providing for us; for as we long for food, so He that we may be saved. And hear how in all places He revealeth not all off-hand, but first throweth the hearer into perplexity, in order that having begun to seek the meaning of what has been said, and then being perplexed and in difficulty, he may when what he sought appears, receive it the more readily, and be made more attentive to listening. For wherefore said He not at once, “My meat is to do the will of My Father?” (though not even this would have been clear, yet clearer than the other.) But what saith He? “I have meat to eat that ye know not of”; for He desireth, as I said, first to make them more attentive through their uncertainty, and by dark sayings like these to accustom them to listen to His words. But what is “the will of the Father”? He next speaketh of this, and explaineth.
