James 2:19-26
2:19 You believe that God is one; well and good.
Even the demons believe that – and tremble with fear.
2:20 But would you like evidence, you empty fellow, that faith without works is useless?
2:21 Was not Abraham our father justified by works when he offered Isaac his son on the altar?
2:22 You see that his faith was working together with his works and his faith was perfected by works.
2:23 And the scripture was fulfilled that says, “Now Abraham believed God and it was counted to him for righteousness,” and he was called God’s friend.
2:24 You see that a person is justified by works and not by faith alone.
2:25 And similarly, was not Rahab the prostitute also justified by works when she welcomed the messengers and sent them out by another way?
2:26 For just as the body without the spirit is dead, so also faith without works is dead.
