John 6:34

Then said they unto Him, Lord, evermore give us this bread.

That Jesus demanded faith in Himself as a condition of their obtaining salvation, this the Jews now understood. They therefore demanded proof of His ambassadorship and of His ministry, which, as He claimed, elevated Him to the divine rank. It is a most peculiar thing that they did not yet understand the relation between the miracles of Jesus and His divine mission, His deity. They challenge Him to produce some extraordinary sign which would convince them beyond question, which would oblige them to believe. They put the matter so as to make Him responsible for their faith or unbelief. They expect a sign from Him something like that of Moses, who produced manna for the Israelites in the wilderness. They refer to a passage from Scripture, Psalms 78:24, which speaks of this wonderful feeding with bread from heaven. In a way, the expression "bread from heaven" could stand, since the manna had fallen down from the sky with the dew, but at best this was merely a figurative expression. Jesus therefore declares, with great emphasis: Not Moses gave you bread from heaven, but My Father gives you the true Bread from heaven. Even in the desert it was not Moses that gave the children of Israel the manna, and so, at best, Moses can be spoken of in this connection by courtesy only; he had nothing to do with the miracle. But here matters are different; here is the true Bread from heaven given to all men by the Father. He that comes down from heaven with the purpose of giving life to the world, He is the Bread of God, Jesus the Savior. He is the Bread from heaven in deed and in truth, and by His work of giving salvation He establishes that fact beyond doubt. This saying impressed the Jews very deeply; they had but a faint conception of what the Lord might mean in speaking of this wonderful Bread, something like the woman of Samaria. They begged Jesus that He would always, at all times, give them that bread. Their understanding was still not clear, but they have caught enough of His earnestness and enthusiasm, and desire plain information. Note: A great deal has been gained if we can get the unbelievers to ask questions concerning Jesus and His salvation, perhaps persuade them of the fact that Christianity in itself is worthwhile, invite them to come to church.
