Justification Does James 2 contradict Romans 4

I read a great article on Justification by Dr. John MacArthur at www.monergism.com. If you have ever read any of the epistles written by Paul you will know that a man is justified apart from works of the law, and he also states if righteousness comes from the law then Christ died needlessly. It is apparent in scripture that a man cannot save himself nor does he want to. But here is the question at hand. How can we reconcile James chapter 2 vs Romans 4 and other Justification by faith alone versus. I believe the key ingredient here is to understand who is doing the Justifying in these texts. In James 2:24 "You see that a man is justified by works, and not by faith alone." Justification before men is in view in here and Justification before God is in view Romans, and the other epistles. James said If a man says he has faith but no works that man's faith is worthless... I believe James was proving to his readers that Righteous works are the necessary proof of saving faith in Jesus Christ before "MEN". So logically if a man says he has faith, but he is unrighteous, and his acts do not back up his claims; then his faith is worthless. Works is the justifying ingredient to "MEN" and faith is the justifying ingredient to "GOD". With that statement being said you can see who is how Romans 3:30 points out who is justified and who is doing the justifying. 30 "by the works of the Law no flesh will be justified in His sight" In who's sight? God's sight.Who will not be justified, (MAN) any flesh that uses the law to justify themselves to GOD.
