Churches Involvement in Justice Issues

Perhaps if we, as churches, got involved in Justice Issues on a local level it would be an opportunity to practically share the boundless love and amazing grace to all our neighbors.

Or maybe a better first question is something like: "If tomorrow your church simply did not exist anymore, would it be missed in your community?" 

Below is a link to an article that mentions some practical ways that we might engage in the justice issues represented in our communities.
