We recommend that you do not put any vehicle out on the road that you are not willing to lose. We suggest purchasing an inexpensive, older, reliable car for evangelizing. It is none of the State's business whether or not we have insurance on our vehicles. They cannot require the Church, as the nation of God, to have insurance. We are not under their supervision.
Car insurance is a requirement for State residents.
As residents of the nation of Heaven, we are not required to carry insurance. However, God does require that we be responsible for our actions. If we hurt someone or damage property, we should attempt to make restoration, to the best of our ability. In Psalm 91, we have God's assurance that He will deliver His own in times of trouble. The Embassy of Heaven has tapes and books to help you evangelize in a Kingdom of Heaven vehicle.
