James 2:14-17 (ESV)
What good is it, my brothers, if someone says he has faith but does not have works? Can that faith save him?  If a brother or sister is poorly clothed and lacking in daily food,  and one of you says to them, "Go in peace, be warmed and filled," without giving them the things needed for the body, what good is that?  So also faith by itself, if it does not have works, is dead.
More or less I will agree with this statement faith by itself, if it does not have works, is dead. Yet, faith will manifest itself in works. It just will. Though those works might not always be so different from the things you did before you came to faith. And neither do I think Christians have to be afraid of works, as if just by doing them they will fall into some sort of justification by works doctrine. But I would also like to say that the reverse of this statement is also true. And if your faith isn’t in Christ, then your works are to no avail. And your works won’t quicken faith. Only the gospel bears the fruit of faith which in turn bears the fruit of works.
