Faith, like light, should always be simple and unbending; while love, like warmth, should beam forth on every side, and bend to every necessity of our brethren.
Martin LutherWhen God's righteousness is mentioned in the gospel, it is God's action of declaring righteous the unrighteous sinner who has faith in Jesus Christ. The righteousness by which a person is justified (declared righteous) is not his own but that of another, Christ.
Martin Luther
