John 6:56-58

Amplified Bible

⁵⁶ 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. ⁵⁷ Just 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. ⁵⁸ This 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.”
