[chette777]

This is written to Israel primarily. they were Israelite's by birth but not sons of God by birth as they were supposed to be. that is why in chapter three Jesus tells them unless a man be born again. Israelite's needed to be born again to be sons of God rightfully hence the next verse John 1:13 Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
