I dunno about that:
(James 2:14-26)If you say that you believe something, yet never act on that
What good is it, my brothers and sisters, if you say you have faith but do not have works? Can faith save you? If a brother or sister is naked and lacks daily food, and one of you says to them, “Go in peace; keep warm and eat your fill,” and yet you do not supply their bodily needs, what is the good of that? So faith by itself, if it has no works, is dead.
But someone will say, “You have faith and I have works.” Show me your faith apart from your works, and I by my works will show you my faith. You believe that God is one; you do well. Even the demons believe—and shudder. Do you want to be shown, you senseless person, that faith apart from works is barren? Was not our ancestor Abraham justified by works when he offered his son Isaac on the altar? You see that faith was active along with his works, and faith was brought to completion by the works. Thus the scripture was fulfilled that says, “Abraham believed God, and it was reckoned to him as righteousness,” and he was called the friend of God. You see that a person is justified by works and not by faith alone. Likewise, was not Rahab the prostitute also justified by works when she welcomed the messengers and sent them out by another road? For just as the body without the spirit is dead, so faith without works is also dead.
belief, can it really be said that your belief means anything?
No, but there's a difference between telling people that they have to go out and do works to be saved, and telling them that if they do not have the fruit of works resulting from faith, they'd better examine themselves to see if they are in the faith.
I'm afraid that a misplaced emphasis on works could lead someone with an intellectual *faith* to think that by adding works they're OK, when they're not.
Saving faith will produce the fruit of the Spirit as well. So simply adding good works to intellectual assent won't save anyone.
