John 6:51; John 6:53-56

51 I am the living bread that came down from heaven. If anyone eats of this bread, he will live forever. And the bread that I will give for the life of the world is my flesh."

53 So Jesus said to them, "Truly, truly, 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 feeds on my flesh and drinks my blood has eternal life, and I will raise him up on the last day.

55 For my flesh is true food, and my blood is true drink.

56 Whoever feeds on my flesh and drinks my blood abides in me, and I in him.
