In the 21st, more and more people loves to enjoy the life as a "materialist". Chinese people, although got a huge progress in economic, politics, military and manufactory field, our culture competence are far worse than most foreign country especially Western country. So, some people said our people as a "race which lost spirit". Compared to our neighbor country, who also got extensive peogress in economic, manufactory feild, etc. Japan, with the logan of "leaping from Asia to Western". South Korea, as the Christian population skyrocketing, their spirituality is also far better than oueselves, that is astoning to us and even a "dangerous sign". 

Christianity supports a country to be powerful. as my point of view. Around 30-50A.D, one of apostles of Jesus Christ-Paul the Saint, visited Roman Empire and spread Christianity or Jesus Gospel to Roman people. Roman people gradually gave up their old belief to Olympics Gods and turned to face to the one real God-The Creator, Holy Father Jehovah with Holy Infanty Jesus Christ with Holy Spirit". When Constantine the Great finally accepted Christianity as "National Religion", eight of ten of Romans are Christians at all. Most European country held Christianity as national religion or citizens belief and as a common sense, European country are most powerful country in all kinds of fields in that generations or even today. What thing supports the powerfulness and the strenth-by coincidence?? Or the Christianity belif?? United States, although do not have a "contitutional national belief" but has most Christian population than any other country.About 2.5hmillion to 3hmillion people belived in Christ.
