Don't tear down that wall!
I was reading through Nehemiah 1 recently and was struck by how Nehemiah mourned the loss of Jerusalem's walls and the scattering of her people. You see, walls are vital to ancient cities. They were your first and best line of defense against invading forces.
If you didn't have walls you essentially didn't have a city. This is because basically any army could just roll into town, set up shop, and take over without a fight. The walls around an Ancient city structure and security from outsiders, defines the borders, and creates a safe place within it's walls.
Taking this concept to the home, your leadership is the wall protecting the spirit of your family. Your leadership protects your family from negative outside influences, defines the boundaries of what is acceptable and creates a place where it is safe to relax and be at ease. Build your wall, lead your family.
