Anyone who is to find Christ must first find the church. How could anyone know where Christ is and what faith is in him unless he knew where his believers are?
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
