John 6:53-56 NIV

[53] Jesus said to them, “Very truly I tell you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. [54] Whoever eats my flesh and drinks my blood has eternal life, and I will raise them up at the last day. [55] For my flesh is real food and my blood is real drink. [56] Whoever eats my flesh and drinks my blood remains in me, and I in them.
