Still can't understand, whether something is true or not, why let yourself get eaten if avoidable? I believe God wants us to live. What good is a bunch of dead believers?
Let's turn this around a bit......
"Why go off to war? You'll just get a bunch of folks dead. Why not just learn how to speak the other guys language? And, 50 years from now, the 'enemy' will have switched to become your trading partner.
Why rush into a burning building? It may collapse on you and them other folks are probably dead anyway."
Is there NOTHING worth dying for?
Those situations are not at all like dying for God. You go to war to save other humans, you run into a burning building to save others. What does being a martyr accomplish?
