[b.] The nature of this change, and what that is which is wrought; it is spirit, John 3:6. Those that are regenerated are made spiritual, and refined from the dross and dregs of sensuality. The dictates and interests of the rational and immortal soul have retrieved the dominion they ought to have over the flesh. The Pharisees placed their religion in external purity and external performances; and it would be a mighty change indeed with them, no less than a new birth, to become spiritual.
