John 6:51-53

Amplified Bible, Classic Edition

⁵¹ I [Myself] am this Living Bread that came down from heaven. If anyone eats of this Bread, he will live forever; and also the Bread that I shall give for the life of the world is My flesh (body).

⁵² Then the Jews angrily contended with one another, saying, How is He able to give us His flesh to eat?

⁵³ And Jesus said to them, I assure you, most solemnly I tell you, you cannot have any life in you unless you eat the flesh of the Son of Man and drink His blood [unless you appropriate His life and the saving merit of His blood].
