John 1:13-14

13 who were born, not of blood nor of the will of the flesh nor of the will of man, but of God.

6 "That which is born of the flesh is flesh, and that which is born of the Spirit is spirit.

John 6:51-56

51 "I am the living bread that came down out of heaven; if anyone eats of this bread, he will live forever; and the bread also which I will give for the life of the world is My flesh."

52 Then the Jews began to argue with one another, saying, "How can this man give us His flesh to eat?"

53 So Jesus said to them, "Truly, truly, I say to you, unless you eat the flesh of the Son of Man and drink His blood, you have no life in yourselves.

54 "He who eats My flesh and drinks My blood has eternal life, and I will raise him up on the last day.

55 "For My flesh is true food, and My blood is true drink.

56 "He who eats My flesh and drinks My blood abides in Me, and I in him.
