Luther insisted that although salvation is by faith alone, it is never by a faith that is alone. Luther also wrote that even this faith is never alone. He wrote, "When we have thus taught faith in Christ, then we also teach good works. Because thou hast laid hold upon Christ by faith, through whom thou art made righteous, begin now to work well. Love God and thy neighbor, call upon God, give thanks unto Him, praise Him, confess Him. Do good to thy neighbor and serve Him: fulfill thine office. These are good works indeed which flow out of this faith."
