We are to help God in the ongoing work of creation. And God creates by organizing chaos into relationships. That's our job, too. To coordinate and care for the connectedness of the created world. Connectedness, you see, is the natural order.
Sin is a severing of relationships.
It is sin when we cut ourselves off from the natural world. It is sin when we cut ourselves off from families, friends. It is also sin when we cut the cords which connect us to our fellow Christians. But we were created to be connected to one another, and we must treasure the connecting links between churches, especially during trying times. We must treasure the community of connections which is the Christian church.
