Your mind feels like its slogging its way through mud. Everything gets affected because everything is connected. Your body mobilizes, your saliva starts secreting, you can feel the ache in the back of your jaw just anticipating that lemon in your mouth. Everything is connected. Every one gets pulled in and tries to compensate for the part of the system that's broken.
Families are an interconnected system of relationships.
That's the basis of community. It's the way God designed life. Even the physicists recognize this reality in the physical world. What happens to one affects the others. Paul illustrates how this principle works in relational community.
