Faithfulness and loyalty are two different things. They may have a lot in common but one will always be more pristine than the other. We are loyal when we know which side we should be in and leaving or quitting will never be an option because we don't have the heart to see that side crumble. We won't be part of any attempt to hurt that party. When we are faithful, the big difference is we are never doing things out of guilt or obligation. We stay because we trust that we are loved and taken cared of.
