I don't believe we are able to accurately judge someone by their deeds, for we are unable to see the true intent of the heart. God can though. The heart is wicked above all things who can know it? I could do many good deeds as far as human standards apply, but if my deeds are not wrought in God through the Spirit, and out of love, they mean nothing. Professing Christ in true faith is a more fruitful deed than helping many people in your own righteous motivation. Our good works and sacrifices stem from the divine love revealed to us. Anything done lacking the love given to us to do it is worthless. Though our intention may be good, without the God given love as motivation, and our God given faith, it is not considered good works. Faith without works is dead does not mean you must physically help anyone whenever possible, it means that if you have faith your works will show through it. James is not saying if you have faith then you must have works, He is saying simply that it is impossible to have one without the other. Show me your faith without works, and I will show you my faith by my works. Faith produces worthy works is what he is stating. He is not judging those who claim Christ and do nothing, He is saying that works is the proof of faith, you can not have one without the other. Like I said, I could constantly do good works, deeds, but without faith they are dead works.
