How does a true Christian respond to terrorism?

If you believe in the Holy Bible, you believe in 1 thing of many.
That we should not live in fear of man.
Muslims are people, maybe not the most peaceful, harmony-loving people on earth, but they are people. Matthew 10: 28-29 reads, " Do not be afraid of those who kill the body but cannot kill the soul, Rather be afraid of the one who can destroy both the body and soul in hell." Last time I checked, men didn't have that power, no matter how radical, or weapons-equipped they were. There, are too many Christians today, who's fear of Muslims, communists, or liberals is a sign of a weak faith to non-believers around them. What would really happen if Muslims took over our country? (mind you, they'd have to be quite the dashing and persuasively political type, the type to embrace all of our nation's diverse, and contradicting beliefs.) If Muslims took over our country in another more militant way, what would happen to the true Christian church? would it crumble? or would it be in a sense purified through trials and dangerous risks instead of Christianity further becoming a social preference, homogenized and perverted by individualism, lesse-faire capitalism, and ear-tickling televangelists who sell "success" rather than challenge the body of Christ to drop their personal ambitions and live altruistically. The Body of Christ in our country would become like the small, risk taking groups of believers in other countries who are murdered daily for their belief in Christ. I'll tell you one thing, you'd know who was really a Christian and who was walking the fence. Fear not. "Set your mind on things above, not on earthly things." this verse in scripture doesn't mean we should be naive about the world's problems, or ignorant about their solutions, it means we should not forget that this world is not our home. Yes I believe it is definitely our responsibility to vote as biblically as we can and our duty to change the atrocities and affronts to humanity's future such as abortion and the careless disregard for the environment and the poor. But we should remember that God is not dead. He is still in control, and we as Christians need to have faith that (if it truly lies deep in our souls) cannot be whisked away by any force of man.
