Then said they unto him, What shall we do, that we might work the works of God?

Augustine of Hippo
AD 430
He does not say, That you believe Him, but, that you believe in Him. For the devils believed Him, and did not believe in Him; and we believe Paul, but do not believe in Paul. To believe in Him is believing to love, believing to honor Him, believing to go to Him, and be made members incorporate of His Body. The faith, which God requires of us, is that which works 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. 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 believes. And therefore our Lord would not separate faith from works, but said that faith itself was the doing the work of God; He said not, This is your work, but, This is the work of God, that you believe in Him: in order that he that glories might glory in the Lord.
Toeat then that meat which endures to everlasting life, is to believe in Him. Why do you makeready your tooth and your belly? Only believe, and you have eaten already. As He called onthem to believe, they still asked for miracles whereby to believe; They said therefore to Him, What sign show you then, that we may see and believe You? What do you work? .
Or thus; Our Lord sets Himself above Moses, who did not dare to say that He gave the meat which perishes not. The multitude therefore remembering what Moses had done, and wishing for some greater miracle, say, as it were, you promise the meat which perishes not, and does not works equal to those Moses did. He gave us not barley loaves, but manna from heaven.
As if He said, That manna was the type of this food, of which I just now spoke; and which allmy. miracles refer to. You like my miracles, you despise what is signified by them. This bread which God gives, and which this manna represented, is the Lord Jesus Christ, as we read next, For the bread of God is He which comes down from hearer, and gives life to the world.
As the woman of Samaria, when our Lord told her, Whosoever drinks of this water shall never thirst, thought He meant natural water, and said, Sir, give me this water, that she might never be in want of it again: in the same way these say, Give us this bread, which refreshes, supports, and fails not.
