There are a few things that the church as the church has to do: preaching, prayer, ordinanances, church discipline. Other things, like caring for poor unbelievers, are things that Christians have to do, but the church as the church doesn't have to do.
That's why it's tempting to focus on common grace good deeds. People like us feeding the hungry. The problem with trying to do things that make unbelievers like you is that unbelievers hate God.
