A Proper Gospel Way

Obey God and do the works of the law by gospel principles and means. This is the rare and excellent art of godliness, in which every Christian should be a skilled expert. Many people labor for years trying to live a godly life. However, they give it up in shame and confusion because they never understood this holy art. They never tried to attain true godliness in a proper gospel way.
