There are two world religions that are renowned for having followers devoted enough to give up everything--including their lives--for the propagation of their faith. One flourishes in places where critical examination is usually non-existent, and often punishable by imprisonment or death. The other flourishes in places where critical examination is widespread. Regarding the latter, I can think of people who set out to prove this religion wrong but ended up embracing it. Investigative journalist Lee Strobel, college student Josh McDowell, Cambridge University professor C.S. Lewis, U.S. Army General Lew Wallace, and singer Keith Green all came to faith in Jesus Christ after critical and/or hostile examination.
To further distinguish Christianity from Islam, it has for 2000 years flourished in many places where its followers are seemingly powerless minorities subjected to severe persecution. Islam does not flourish in such places. The difference is that Islam needs worldly power to thrive, while Biblical Christianity actually is often purer and more effective when its adherents have no power.
"So what's your point?" Thank you for asking! The Muslim is usually willing to give up everything because he doesn't know any better. Those whom I know of who follow Jesus and are willing to give up everything have heard from many alternative world views and found them inferior.
