Some believed that salvation is achieved through trying our best to live up to the commandments. Others believe that salvation is a free gift from God.
One side will argue that a human can never do enough to earn salvation. The other side will counter that we are still expected to try to do our best.
Perhaps the key is found in the salvation itself. is it earned or is it given?
