In re the discussion on the words "tribulation" vs "wrath":  Tribulation is something that happens to someone who is the victim of someone else's wrath.  Believers will suffer tribulation from the wrath of the Beast.  Unbelievers will suffer tribulation at the wrath of God.  We are not promised deliverance from the wrath of the Beast and we are in fact told that many believers will die from his wrath.  In fact all around the world many believers today are dieing from the wrath of Muslim or atheistic governments.
