The Christian's justification by Faith alone apart from works

"A good or bad house does not make a good or bad builder; but a good or bad builder makes a good or bad house. And in general, the work never makes.workman like itself, but the workman makes the work like himself. So it is with the works of man. As the man is, whether believer or unbeliever, so also is his work - good if it was done in faith, wicked if it was done in unbelief. But the converse is not true, that work makes the man either a believer or an unbeliever. As works do not make a man a believer, so also they do not make him righteous. But as faith makes a man a believer and righteous, so faith does good works. Since, then, works justify no one, and a man must be righteous before he does a good work, it is very evident that it is faith alone which, because of the pure mercy of God through Christ and in his Word, worthily and sufficiently justifie and saves the person. A Christian has no need.of any work or law in order to be saved since through faith he is free from every law and does everything out of pure liberty and freely." - Martin Luther, The Freedom of a Christian, Pg. 37
