John 1:12-13

12But to as many as did receive and welcome Him, He gave the right [the authority, the privilege] to become children of God, that is, to those who believe in (adhere to, trust in, and rely on) His name—

13who were born, not of blood [natural conception], nor of the will of the flesh [physical impulse], nor of the will of man [that of a natural father], but of God [that is, a divine and supernatural birth—they are born of God—spiritually transformed, renewed, sanctified].
