Ignorance, whether deliberate or not, is neither Christian nor patriotic. Pastors would do well to educate their congregations on the true nature of the world we live in and make sure they understand that their true hope...their only hope...is in Jesus. And that His Kingdom, yet to be revealed, will not be a matter of majority vote.
Democracy...even the ideal democratic republic...is still the antithesis of the Kingdom of God. Any love of country, if it is not God's Kingdom, is love stolen from that which belongs to God. To pin your hope on any man, other than Jesus, is sheer nonsense, foolishness and a waste of one's short time on this earth.
