John 6:29

What then did they? As though they had heard nothing, they said, "What shall we do, that we might work the works of God?" This they said, not that they might learn and do them, (as the sequel shows,) but to induce Him again to supply them with food, and desiring to persuade Him to satisfy them. What then saith Christ? "This is the work of God, that ye believe on Him whom He hath sent." On this they asked, "What sign showest thou, that we may see and believe?" Nothing more senseless, nothing more unreasonable, than these men! While the miracle was yet in their hands, as though none had been done, they spake after this manner, "What sign shewest thou?" and having thus spoken, they do not even allow Him the right of choosing the sign, but think to force Him to exhibit none other than such a one as was wrought in the days of their fathers; wherefore they say, "Our fathers did eat manna in the wilderness," thinking by this to provoke Him to work such a miracle as might supply them with carnal nourishment. Else why did they mention none other of the miracles of old, though many took place in those times, both in Egypt and at the sea and in the wilderness, but only that of the manna? Was it not because they greatly desired that one by reason of the tyranny of their bellies? Ye who when ye saw His miracle called him a Prophet, and attempted to make Him a king, how is that now, as though none had been wrought, ye have become thankless and ill-minded, and ask for a sign, uttering words fit for parasites, or hungry dogs? Does the manna now seem wonderful to you? Your soul is not now parched up. Mark too their hypocrisy. They said not, "Moses did this sign, what doest thou?" thinking it would annoy Him; but for a while they address Him with great reverence, through expectation of food. So they neither said, "God did this, what doest thou?" that they might not seem to make Him equal with God; nor did they bring forward Moses, that they might not seem to lower Him, but put the matter in an intermediate form, "Our fathers did eat manna in the wilderness." He indeed might have replied, "I, but now, have wrought greater wonders than did Moses, requiring no rod, having no need of prayer, but doing all of Myself; and, if ye call to remembrance the manna, see, I have given you bread." But this was not the season for such speeches; and the one thing He earnestly desired was, to bring them to spiritual food.

(Tr. xxv. in Joan) He does not say, That ye believe Him, but, that ye believe on Him. For the devils believed Him, and did not believe on Him; and we believe Paul, but do not believe on Paul. To believe on Him is believing to love, believing to honour Him, believing to go unto Him, and be made members incorporate of His Body. The faith, which God requires of us, is that which worketh by love. Faith indeed is distinguished from works by the Apostle, who says, That man is justified by faith without the deeds of the law. (Rom. 3:28) But the works indeed which appear good, without faith in Christ, are not really so, not being referred to that end, which makes them good. For Christ is the end of the law for righteousness to every one that believeth (Rom. 10:4). And therefore our Lord would not separate faith from works, but said that faith itself was the doing the work of God; He saith not, This is your work, but, This is the work of God, that ye believe on Him: in order that he that glorieth might glory in the Lord.

"They said therefore unto Him, What shall we do, that we may work the works of God?" For He had said to them, "Labor not for the meat which perisheth, but for that which endureth unto eternal life." "What shall we do?" they ask; by observing what, shall we be able to fulfill this precept? "Jesus answered and said unto them, This is the work of God, that ye believe on Him whom He has sent." This is then to eat the meat, not that which perisheth, but that which endureth unto eternal life. To what purpose dost thou make ready teeth and stomach? Believe, and thou hast eaten already. Faith is indeed distinguished from works, even as the apostle says, "that a man is justified by faith without the works of the law:" there are works which appear good, without faith in Christ; but they are not good, because they are not referred to that end in which works are good; "for Christ is the end of the law for righteousness to every one that believeth." For that reason, He willeth not to distinguish faith from work, but declared faith itself to be work. For it is that same faith that worketh by love. Nor did He say, This is your work; but, "This is the work of God, that ye believe on Him whom He has sent;" so that he who glories, may glory in the Lord.

Christ, though He saw it would not avail, yet for the good of others afterwards, answered their question; and showed them, or rather the whole world, what was the work of God: Jesus answered and said unto them, This is the work of God, that ye believe on Him whom He hath sent.
