The ninth question in Brian McLaren's book 'A new kind of Christianity' is the 'Pluralism question'.
Another way of asking the question is: the majority world doomed, because they do not acknowledge Jesus as their Lord and Saviour.
I've always been on the same wave length as McLaren on this one. He uses 2:1-29
...people are never judged based on knowledge they don't have, and that God well bless
McLaren also takes time in writing about Jesus and his claims of John 14:6. "I am the way and the truth and the life. No one comes to the Father except through me." Though good exegesis he makes the point that it was a message for his disciples. Not for those outside the room or the generations to come. Interesting and probably open to debate.
My belief is that if God is one of love. He can see through the crap and into the heart, no mater what the culture.
