Skylar and Dan are happily celebrating their wedding when suddenly the Rapture occurs. Skylar's Christian parents are raptured, leaving their daughter and her new husband behind. She and Dan must find shelter from the new, extreme weather as well as from several winged demons that are keen on making Skylar and Dan their prey. They manage to take shelter in a nearby church along with several others remaining, where they re-examine their lives and personal faith in Jesus Christ, in the wake of remaining on Earth as it enters the seven years of Tribulation. The ending results in the final trumpet being blown from Heaven as thousands upon millions of fallen angels descend to Earth to finish off the human race.

That sounds a lot like the Left Behind movies, which were really good. I'm going to be on the lookout for this one.

Yes it didn't have a great box office but you're correct about others that never make it.
