John 6:33-36

For the Bread of God is He who comes down out of heaven, and gives life to the world.” Then they said to Him, “Lord, always give us this bread.” Jesus replied to them, “I am the Bread of Life. The one who comes to Me will never be hungry, and the one who believes in Me [as Savior] will never be thirsty [for that one will be sustained spiritually]. But as I told you, you have seen Me and still you do not believe.
