Ironically, Christians who shun politics to supposedly advance the Gospel are actually allowing others to stop the Gospel. How so? Because politics and law affects one’s ability to preach the Gospel! If you think otherwise, visit some of the countries I have visited—Iran, Saudi Arabia and China. You cannot legally “preach the Gospel” in those countries—or practice other aspects of your religion freely—because politically they’ve ruled it out as they have in North Korea.
In fact, politics affects virtually every area of your life through the laws made by government. So if you care about your family, business, church, school, children, money, property, home, security, healthcare, safety, freedom, and your ability to “preach the Gospel,” then you should care about politics. — Frank Turek (from, You Can’t Preach the Gospel without Freedom)
