I have tried to sketch out a blog article on this very topic for some time, but could never say it this well. So I’m going to link to this short essay by John Pavlovitz, posted last year in Relevant.
By the way, a lot of people wrote back to the author and claimed he was “afraid to take a stand, given that the sky is falling!” I think they misunderstood his article, or have mistaken theology.
Open Our Eyes, Lord!
