John 6:52-58

52Then the Jews began to argue with one another, saying, “How can this man give us His flesh to eat?”

53And Jesus said to them, “I assure you and most solemnly say to you, unless you eat the flesh of the Son of Man and drink His blood [unless you believe in Me as Savior and believe in the saving power of My blood which will be shed for you], you do not have life in yourselves.

54The one who eats My flesh and drinks My blood [believes in Me, accepts Me as Savior] has eternal life [that is, now possesses it], and I will raise him up [from the dead] on the last day.

55For My flesh is true [spiritual] food, and My blood is true [spiritual] drink.

56He who eats My flesh and drinks My blood [believes in Me, accepts Me as Savior] remains in Me, and I [in the same way remain] in him.

57Just as the living Father sent Me, and I live because of the Father, even so the one who feeds on Me [believes in Me, accepts Me as Savior] will also live because of Me.

58This is the Bread which came down out of heaven. It is not like [the manna that] our fathers ate and they [eventually] died; the one who eats this Bread [believes in Me, accepts Me as Savior] will live forever.”
