“Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.”
King James Version (KJV)
1:13 Who were born - Who became the sons of God, not of blood - Not by descent from Abraham, nor by the will of the flesh - By natural generation, nor by the will of man - Adopting them, but of God - By his Spirit.
Joh 1:13 Who were born, not of blood, nor of the will of the flesh. The Jews prided themselves on being Abraham's children, and trusted in their blood for salvation. To be a son of God is not a fleshly birth at all, but the spirit of the subject is "born of God". The Savior explains the birth more particularly, in Joh 3:1-8.
