John 6:27

6:27 Do not work for the food that disappears, but for the food that remains to eternal life – the food which the Son of Man will give to you. For God the Father has put his seal of approval on him.”

John 6:50-58

6:50 This is the bread that has come down from heaven, so that a person may eat from it and not die. 6:51 I am the living bread that came down from heaven. If anyone eats from this bread he will live forever. The bread that I will give for the life of the world is my flesh.”

6:52 Then the Jews who were hostile to Jesus began to argue with one another, “How can this man give us his flesh to eat?” 6:53 Jesus said to them, “I tell you the solemn truth, unless you eat the flesh of the Son of Man and drink his blood, you have no life in yourselves. 6:54 The one who eats my flesh and drinks my blood has eternal life, and I will raise him up on the last day. 6:55 For my flesh is true food, and my blood is true drink. 6:56 The one who eats my flesh and drinks my blood resides in me, and I in him. 6:57 Just as the living Father sent me, and I live because of the Father, so the one who consumes me will live because of me. 6:58 This is the bread that came down from heaven; it is not like the bread your ancestors ate, but then later died. The one who eats this bread will live forever.”
