Good works

"What doth it profit, my brethren, though a man say he hath faith, and have not works? can faith save him?"

"For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:"

"Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin."

"Epistle to the Romans 3:20 (KJV)"

"Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified. [...]"

"One ought to fast, watch, and labor to the extent that such activities are needed to harness the body’s desires and longings; however, those who presume that they are justified by works pay no attention to the need for self-discipline but see the works themselves as the way to righteousness. They believe that if they do a great number of impressive works all will be well and righteousness will be the result. Sometimes this is pursued with such zeal that they become mentally unstable and their bodies are sapped of all strength. Such disastrous consequences demonstrate that the belief that we are justified and saved by works without faith is extremely foolish."
