John 6:54-56

Amplified Bible

⁵⁴ 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. 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.
