Faith without works is dead being alone. Was not Abraham justified by works? He could not just say I have faith in you God... his faith was tested before righteousness was imputed on him by God. Cleanse your hands you sinners, and purify your hearts. But these people speak evil things about that which they know not. They know what they see naturally, and these very things corrupt their minds. These are the people who separate themselves speak great things to puff up their egos amongst men, but do not have the living Spirit of Christ in them.
