Grace is not of an equal extent to nature: grace is not native, but donative; not by generation, but by regeneration. It is from the Father of spirits, not fathers of our flesh. Who can bring a clean thing out of filthiness? The new birth is "not of blood, nor of the will of the flesh, nor of the will of man" (John 1:13).
It teaches us humility. As we were from Adam, so he was from the dust of the earth, and that dust from nothing. Our father was Adam, our grandfather dust, our great-grandfather nothing.Exposition Epistle of Jude, 299
