It is an expression frequently used instead of "regeneration," to express the change from the natural state of sin to the new spiritualized life of the Christian. It is dying unto sin and being born again unto righteousness, a complete transformation of our moral nature, a new heart Following after conversion and justification, the new birth or regeneration brings about a complete change of heart (see Heb. 1022; Gal. 6:15; II Cor. 5:17; Col. 3:9; Eph. 4:22-24 and other passages).
