i am surprised. i thought you knew more about religion as you talk about it with "relative" frequency.
1. to go with Dr. Pep, the old testament in the Christian faith is the Torah in the Jewish faith...and it is also part of the Muslim faith. Islam also considers Jesus a prophet, so it would seem that that is proof enough.
2. "created" equal. you and i are not the same, as Australians are different from New Zealanders and Argentines and Tanzanians. we all make choices--to kill, to covet, to what have you. that is "free will", which as i said i another post is the greatest/worst gift granted to man.
it is not for me to say if they will go to heaven or not. i will say that the Bible says that Jesus will not return till every man has had the chance to hear of Christ. so, it seems we all have a bit more time to figure these things out for ourselves.
3. and this is the most absurd, really? what makes you think most Christians are white? have you heard of Catholics? and as the world traveler you are, i would assume that you know that central and south america is over 90% Catholic--and correct me if i am wrong, they are hispanic, which is a different box in the race section of my job application.
also, you cannot really count many europeans. most french are "catholic" and atheists. notice where i put the quotes...catholic by birth, atheist by belief.
and the underground churches in China--that is a huge chunk of population...South Korea...i have missionary friends throughout Africa. i gotta disagree on the white Christian thing.
these are my thoughts and in no way should they be misconstrued as a biblical scholar responding to your questions. i hope this helps.
