True faith requires work - Wilford W. Anderson

Faith in the Savior requires more than mere belief. The Apostle James taught that even the devils believe and tremble. But true faith requires work. The difference between the devils and the faithful members of this Church is not belief but work. Faith grows by keeping the commandments. We must work at keeping the commandments. From the Bible Dictionary we read that “miracles do not produce faith but strong faith is developed by obedience to the gospel of Jesus Christ; in other words, faith comes by righteousness.”
