"...nor of the will of the flesh" (Jn. 1:13)
"...who were born, not of blood nor of the will of the flesh nor of the will of man, but of God." (Jn. 1:13). The Bible declares there are only two states of being: flesh and Spirit, (regenerate or unregenerate) and that it is only those who are born of the Spirit (Jn. 3:6, 6:63)* who will infallibly come to Jesus (Jn. 6:37, 6:65)**. The native resources of the flesh are, therefore, morally impotent to meet God's humbling requirement to believe the gospel. (1:13)
* "That which is born of the flesh is flesh, and that which is born of the Spirit is spirit."
* "It is the Spirit who gives life; the flesh is no help at all..."
** "All that the Father gives me will come to me"
** "This is why I told you that no one can come to me unless it is granted him by the Father."
