John 6:33, 35, 51, 53-56

For the Bread of God is He who comes down out of heaven, and gives life to the world.”

Jesus replied to them, “I am the Bread of Life. The one who comes to Me will never be hungry, and the one who believes in Me [as Savior] will never be thirsty [for that one will be sustained spiritually].

I am the Living Bread that came down out of heaven. If anyone eats of this Bread [believes in Me, accepts Me as Savior], he will live forever. And the Bread that I will give for the life of the world is My flesh (body).”

And 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. The 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. For My flesh is true [spiritual] food, and My blood is true [spiritual] drink. He 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.
