James 2:19

17Even so faith, if it hath not works, is dead, being alone.

18Yea, a man may say, Thou hast faith, and I have works: shew me thy faith without thy works, and I will shew thee my faith by my works.

19Thou believest that there is one God; thou doest well: the devils also believe, and tremble.

20But wilt thou know, O vain man, that faith without works is dead?

21Was not Abraham our father justified by works, when he had offered Isaac his son upon the altar?
