The Bible is a spiritual book about spiritual things. And interestingly enough, even non-believers would agree with that. They may not believe any of the spiritual things in that spiritual book, but they do understand that it is a spiritual book about spiritual things.
But the Bible is also a practical book about practical things. Actually, it would be most accurate to say it is a spiritual book about spiritual things that are to be authoritative even in practical things. And that is where non-believers and even a few mushy believers begin to disagree. They do not believe that the spiritual truths in the Bible are to dictate every aspect of our practical lives; they generally believe that the spiritual and the practical are to be completely separate, with an impenetrable wall between them.
Nowhere is this more clearly seen than in the realm of politics. To some, the words “separation of church and state,” though found neither in the Bible nor in the Constitution, are as the very words of God written in stone by His finger.
But Scripture itself tells a vastly different story, one that should have every believer gladly and actively participating in the political process.
In Matthew 14, John the Baptist, a preacher, confronted Herod, a politician, not just over a matter of morality, but also a matter of legality, saying, “It is not lawful for thee to have her.”
