Sanctified political action is a good and even necessary thing which should be pursued. But if we don’t change the hearts of the people we are going to lose the culture, and then the nation itself, and no law or politics will be able to stem that tide. The church can function without government support. It's terribly undesirable, inconvenient and painful, as we abundantly see in persecuted nations, but it can be done. But the church cannot function with the personal testimonies of the saints.
