John 6:30-40

They said therefore unto him, What then doest thou for a sign, that we may see, and believe thee? what workest thou? Our fathers ate the manna in the wilderness; as it is written, He gave them bread out of heaven to eat. Jesus therefore said unto them, Verily, verily, I say unto you, It was not Moses that gave you the bread out of heaven; but my Father giveth you the true bread out of heaven. For the bread of God is that which cometh down out of heaven, and giveth life unto the world. They said therefore unto him, Lord, evermore give us this bread. Jesus said unto them, I am the bread of life: he that cometh to me shall not hunger, and he that believeth on me shall never thirst. But I said unto you, that ye have seen me, and yet believe not. All that which the Father giveth me shall come unto me; and him that cometh to me I will in no wise cast out. For I am come down from heaven, not to do mine own will, but the will of him that sent me. And this is the will of him that sent me, that of all that which he hath given me I should lose nothing, but should raise it up at the last day. For this is the will of my Father, that every one that beholdeth the Son, and believeth on him, should have eternal life; and I will raise him up at the last day.
