Paul commands us to love the community of faith, but he goes further and describes how to love others in the world; even our enemies. In a world where some love some people some of the time, and others not at all. What would the world look like if the followers of Jesus love all the world all of the time? It's a hard task, but Paul thinks we are up to it. It means swimming against the current. It also means living by grace freely given to each of us.
