In Protestant doctrine, righteousness is imputed (λογίζομαι, "logizomai") to the inherently ungodly, by grace, through faith in the cross of Christ. Protestantism teaches the concept of fiduciary faith, that is, that "faith alone suffices for justification, and that consequently the observance of the moral law is not necessary either as a prerequisite for obtaining justification or as a means for preserving it." Therefore, a righteousness from God is viewed as being credited to the sinner's account through faith alone, apart from works, being based solely on the blood of Christ.
