Well Islam poses a threat re: both death and spiritual death...but usually posters like yourself simply ignore the spiritual death component and simply weigh ONLY the physical death issue...as if that's all there was to life...material naturalism...
Only a fool thinks the "brush fire" here on earth is the three-alarm, city-wide meltdown that hell represents.
Therefore, yes I take our cultural cue from a certain "Lord" named Jesus Christ.
Here's Jesus:
"I tell you, my friends, do not be afraid of those who kill the body and after that can do no more. But I will show you whom you should fear: Fear him who, after the killing of the body, has power to throw you into hell. Yes, I tell you, fear him." (Luke 12:4-5)
So does Jesus say, "fear the terrorists?" (No)
Does Jesus say "Muslims?" (No)
Instead, does He say to exercise fear of the One who has authority to cast somebody into hell? (Yes)
So, indeed, our "fear" is on behalf of those who are placing their eternal spiritual lives at risk.
Interesting, you don't believe that Muslims have the ability to cause someone to place their eternal spiritual life at risk? AFAIK, Islam is very effective at causing its followers to cast themselves into hell. As far as my fears go, physical death is not on the list.....but thanks for speculating.
