That proves that works are a necessary part of faith. If intention is part of sin, meaning if I intend to do something, then I am guilty of doing it. Such as lusting is adultery. Faith is part of works. For if I do good in order to be recognized, I have my treasure, and have still no chance at Heaven. If I do good in order to please God by obeying Him, I have faith in Him. For good works to be good, they must be God's will. If they are not the will of God, they are not good. Therefore, it is the one who loves God and obeys Him that is a truly saved Christian. If they do not, they have are play acting. Thus, works are required to exist if there is faith. If there are no works, there is no faith.
