The Nature of the Church

When we refer to somethings "nature," we are referring to inherent or innate characteristics, attributes, or qualities. For instance, water is wet. That is part of its nature. It should not surprise us when a thing acts or behaves in accordance with its nature. As we look at Romans 1:8-15 we find Paul constantly praying for and longing to visit the church in Rome. What does this passage reveal in regard to the nature of the Church?
