The text tells us:

1. What community is - A large crowd doesn't always match community (v 1-2). Community isn't always the crowd.
2. Community cares enought to carry - Community will help you carry your cross. Love is action (v 3). Sometimes community comes with a cost and you have to carry someon else on thier mat. Sometimes, you have to help them take the roof off. Real community gets you where you need to be.
3. The fith of the community facilitates healing. Communal faith facilitates healing (v 5). Jesus cared about his soul and made sure the whole man was healed (body and soul).
