Christians, a scenario with a question attached for you:?

What if you were in attendance at a national prayer rally that was on live television, and suddenly a group of terrorists burst in wielding guns and machettis as they lined everyone up against the wall...what if then they demanded that you deny JESUS CHRIST is LORD and SAVIOR and profess alleigence to their god, and if you refuse they will take off your head with a machetti? what would you do?
