Solutions? Most of the “solutions” I’ve seen proposed focus on aspects of Christian practice that could be called “style.” Music style, for example. How we worship on Sundays. Now I’m not against music or other aspects of style evolving over time, but our core problem isn’t style. Nor is it “doctrine.” Rather, we have a credibility problem. The reasons I pulled out above highlight this point.
Don’t place your hope in politicians. If you aren’t aware, your hopes will be dashed.
Put your hope in God. Sometimes you may not be sure whether he is alongside or not. That’s part of the deal. He is there.
