I think that Christianity has a real future in Asia, looking at the explosion currently taking place in China. Japan is the one that Christian missionaries have been trying to crack for over a century, and with the current crisis of a critically old population vs. a low young population, another lost decade is in the future. Materialism will struggle, faith will rise. I think a recent survey listed Japan as one of the nations in which atheism had decreased a little since the 90s (along with Germany, weirdly enough).
Christ wants Japan. They just resist a lot.
He desires that all would come to him and kneel at the foot of the Cross and apprehend their Salvation, true that.
many are called, but few are Chosen!
With help from the Americans. Nagasaki was the site of the largest Christian church in the orient, St. Mary's Cathedral. Also had the largest concentration of baptised Christians in all of Japan. (Also the city where the Jesuit missionary, Francis Xavier, established a mission church in 1549.)
The morning of August 9, 1945, a B-29 Superfortress called Bocks Car, took off from Tinian Island to drop Fat Man on Japan. St. Marys Cathedral was one of the landmarks that the Bocks Car bombardier had been briefed on, and looking through his bomb site over Nagasaki that day, he identified the cathedral and ordered the drop. The bomb detonated only 500m away. Mass was well attended that day. The entire Christian community of Nagasaki was wiped out.
