The church that I attend is hopping on the 'social justice' bandwagon! I can't see the point. At best tokenistic, at worst a waste of time.
It's a good question though. Where and to what extent to we bring to the government's attention our disquiet with its actions?
In this case, I think that its going to be about the economic opportunists who want a free ride to Australia when they wouldn't otherwise come in.
Maybe the government's treatment of some needs to be improved, but also, maybe they should be having a lend of us so egregiously. The government's first job is to protect the state (which is why it has the sword...Romans mentions this).
