John 6:53-56

53So Jesus said to them, “Truly I tell you, unless you eat the flesh of the Son of Man and drink his blood, you do not have life in yourselves.

54The one who eats my flesh and drinks my blood has eternal life, and I will raise him up on the last day,

55because my flesh is true food and my blood is true drink.

56The one who eats my flesh and drinks my blood remains in me, and I in him.
