To be honest, until I read this, I never even thought about the point of denying Christ. But you are right, it is something we should never do. Those who died before us did so still claiming Christ is Lord and would not bow down to another god.
Feel free to go into the den of radical Islamists and be martyred. They would be very happy to have all of our heads - Christian and Jewish - to put on their disgusting videos which they show on Al Jazeera. We defeat them by STAYING ALIVE to proclaim the truth - not by dying. Let them die for their "faith" - while we live.
