While many believe James 2 teaches salvation by doing good works, this is not what the passage means. James is actually saying we’re saved by a living faith that involves the one-time decision to open the door of our lives to Jesus Christ (just like Rahab opened the door for the spies) and to offer ourselves to God (just like Abraham offered Isaac). This “living faith” that saves is contrasted against the dead faith that even demons have (James 2:19).
