In the Bible in the Book of Galatians there were some Christians who incorrectly believed that the sacrifice of Christ IN COMBINATION WITH their righteous living had power to obtain salvation. Righteous living does not help obtain salvation but it does make you a candidate for salvation. A candidate is a person who, in freezing weather, has walked to a warm house. Being a candidate does not get them into the house. They are just as cold as if they had not walked to the house. Only God can open the door to the house. Only the sacrifice of Christ alone has power to obtain salvation.
