Religion in Korea, part two Christianity

So what can we say about Christianity in Korea. Well, aparently God is pretty big over here. With religion being a non-issue in Japanese culture, and Christianity so harshly repressed in China, it's hard to imagine that God would take off like the BEATLES arriving in America, when Christianity came to Korea. Those red neon crosses are quite literally everywhere, and at night in some places, it's like Las Vegas meets the vatican.
I'd say about 90 of my Korean friends are Christian, as per Wikipedia a little more than 40 percent of South Koreans profess religious affiliation, but of that 40, 30% call themselves Christian. This is a pretty high number if you consider the short period of time between now and when Korea became free of the Japanese occupation. Christian groups were at the forefront of the occupations resistance, and Christian efforts established alot of schools, universities and hospitals in Koreas days as a third world country, helping to bring South Korea into the modern era.
So Christianity in Korea also has ties to Korean nationalism, which is ironic, because tieing Christianity to Korea's national identity is like replace apple pie in in americana with sushi.
