John 6:29-39 KJV

29 Jesus answered and said unto them, This is the work of God, that ye believe on him whom he hath sent .
30 They said therefore unto him, What sign shewest thou then, that we may see , and believe thee? what dost thou work ?
33 For the bread of God is he which cometh down from heaven, and giveth life unto the world.
35 And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger ; and he that believeth on me shall never * thirst .
37 All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out.
38 For I came down from heaven, not to do mine own will, but the will of him that sent me.
39 And this is the Father's will which hath sent me, that of all which he hath given me I should lose nothing * *, but should raise it up again at the last day.
