This might take a while, but you and your loved ones can have fun placing bets on how long it takes for them to get flustered and leave. Ask them to explain the story of Elisha and the Forty two children. You may have to resort to another method to actually get rid of them, but this will definitely make them sweat. Excuse yourself from the front door and DO NOT come back. Make a series of increasingly reprehensible fake phone calls.
Guys can show an intense interest in their spiel.
Part way through, begin putting on make-up, hosiery, a dress, the whole works. If they're still there when you are done, Ask them if they would please kindly leave as you have a hot date in ten minutes. Look smug and tell them that your God can beat up their God.
