Let the Church be the Church. That means you, right where you are, in you every-day life. I have this hunch that if people just lived the truth instead of trying to package, promote, and push it, they'd be far more effective at influencing their part of the world for the better.
Also conservatives are stupid. We let the liberals determine the rules (frame the debate). Take the term "Social Justice". That is actually is a good term for Pro-Liberty Conservative values. But because the Libs came up with it first. We will let them keep it, instead of explaining how we are the ones who really promote social justice, by defending property rights, religious rights, and other freedoms.
You can say let the church be the church, but if someone wants to give God their best, and not the leftovers. Then they will organize and work together to actually change the laws to make this country a better place for their fellow man. (the whole loving your neighbor thing)
