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 6:54-57

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.
