John 6:33-35,47-58 NKJV
33 "For the bread of God is He who comes down from heaven and gives life to the world." 34 Then they said to Him, "Lord, give us this bread always." 35 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.
47 "Most assuredly, I say to you, he who believes in Me has everlasting life. 48 "I am the bread of life. 49 "Your fathers ate the manna in the wilderness, and are dead. 50 "This is the bread which comes down from heaven, that one may eat of it and not die. 51 "I am the living bread which came down from heaven. If anyone eats of this bread, he will live forever; and the bread that I shall give is My flesh, which I shall give for the life of the world." 52 The Jews therefore quarreled among themselves, saying, "How can this Man give us His flesh to eat?" 53 Then Jesus said to them, "Most assuredly, I say to you, unless you eat the flesh of the Son of Man and drink His blood, you have no life in you. 54 "Whoever eats My flesh and drinks My blood has eternal life, and I will raise him up at the last day. 55 "For My flesh is food indeed, and My blood is drink indeed. 56 "He who eats My flesh and drinks My blood abides in Me, and I in him. 57 "As the living Father sent Me, and I live because of the Father, so he who feeds on Me will live because of Me. 58 "This is the bread which came down from heaven--not as your fathers ate the manna, and are dead. He who eats this bread will live forever."
