John 6:53-58 New King James Version (NKJV)

⁵³ Then Jesus said to them, “Most assuredly, I say to you, unless you eat the flesh of the Son of Man and drink His blood, you have no life in you. ⁵⁴ Whoever eats My flesh and drinks My blood has eternal life, and I will raise him up at the last day. ⁵⁵ For My flesh is food indeed,^[a] and My blood is drink indeed. ⁵⁶ He who eats My flesh and drinks My blood abides in Me, and I in him. ⁵⁷ As the living Father sent Me, and I live because of the Father, so he who feeds on Me will live because of Me. ⁵⁸ This is the bread which came down from heaven—not as your fathers ate the manna, and are dead. He who eats this bread will live forever.”
