Does it not bother any of the christians here that, in all likelyhood, if they had been born in, say, Saudi Arabia, they would almost certainly be Muslim? Like conservative Muslim no less. Or India, likely Hindu.
In essence, logically, your religion is a question of time and space, not faith. Let's not lie. However much faith you may have now, that's a function of being born into a Christian tradition. And were you born in a Muslim, Hindu, etc tradition you would almost certainly have just as much "faith" in those respective religions as you do now.
