John 6:55-57

Amplified Bible

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