Boundaries come in many forms and protect various parts of us. These include physical, emotional, spiritual, financial, and relational. For instance, what is appropriate between a husband and a wife is not appropriate between a mother and a child. What is appropriate between a mother and child is inappropriate between employer and employee. To get the concept in a different way, we invite you to think of the walls around a castle.
People live inside the castle.
There is a moat around the castle with water and other obstacles inside it. There is a bridge across the moat that leads to a drawbridge. People use the drawbridge to enter or leave the castle. There is a trained guardsman at the drawbridge. He knows how to operate the mechanism that raises or lowers the drawbridge.
