When we fail to distinguish between the quasi-Christian civil religion of America and the kingdom of God … we end up wasting precious time and resources defending and tweaking the civil religion — as though doing so had some kingdom value. We strive to keep prayer in schools, fight for the right to have public prayer before football games, lobby to preserve the phrases “under God” in our Pledge of Allegiance and “in God we trust” on our coins, battle to hold the traditional civil meaning of marriage, and things of that sort — as though winning these fights somehow brings America closer to the kingdom of God.
