John 6:35-38

35[And] Jesus said to them, I am the bread of life: he that comes to me shall never hunger, and he that believes on me shall never thirst at any time.

36But I have said to you, that ye have also seen me and do not believe.

37All that the Father gives me shall come to me, and him that comes to me I will not at all cast out.

38For I am come down from heaven, not that I should do my will, but the will of him that has sent me.
