{As a member of the US Air Force, I was deployed to Saudi Arabia in 1993 and 1996. We were allowed to venture into downtown Dahran, but warned never to speak of our beliefs, no matter what faith we were. We were further instructed to hide our crosses/symbols of our faith, lest we get apprehended by the local "religious police." These were the men that patrolled the streets in green uniforms and gleeming white helmets, carrying a rather large baton! I wasn't remotely Christian at the time, but still felt a sharp stab in my freedom of choice!}
Revelation tells all who are suffering that everlasting life is the gift of faithful endurance. Whether it's a migraine or martyrdom, the Lord is reserving a place for those that keep the faith.
