The necessary result of God’s saving work is a transformed person. When a soul is redeemed, Christ gives a new heart (cf. Ezekiel 36:26). Implicit in that change of heart is a new set of desires – a desire to please God, to obey, and to reflect His righteousness. If such a change does not occur, there is no reason to think genuine salvation has taken place.
