53Jesus therefore said to them, “Most certainly I tell you, unless you eat the flesh of the Son of Man and drink his blood, you don’t have life in yourselves.
54He who eats my flesh and drinks my blood has eternal life, and I will raise him up at the last day.
55For my flesh is food indeed, and my blood is drink indeed.
56He who eats my flesh and drinks my blood lives in me, and I in him.
