John 6:27-36

Do not labor for the food which perishes, but for the food which endures to everlasting life, which the Son of Man will give you, because God the Father has set His seal on Him.” Then they said to Him, “What shall we do, that we may work the works of God?” Jesus answered and said to them, “This is the work of God, that you believe in Him whom He sent.” Therefore they said to Him, “What sign will You perform then, that we may see it and believe You? What work will You do? Our fathers ate the manna in the desert; as it is written, ‘He gave them bread from heaven to eat.’ ” Then Jesus said to them, “Most assuredly, I say to you, Moses did not give you the bread from heaven, but My Father gives you the true bread from heaven. For the bread of God is He who comes down from heaven and gives life to the world.” Then they said to Him, “Lord, give us this bread always.” And Jesus said to them, “I am the bread of life. He who comes to Me shall never hunger, and he who believes in Me shall never thirst. But I said to you that you have seen Me and yet do not believe.
