Why is it amazing that Christianity survived?
It is amazing because the gospel depended almost primarily on one man, Paul, who came into gross immorality and commerce, was physically downtrodden, beaten, and not a specimen of health, yet persevered and established churches everywhere, bringing Christianity as we know it today.
Les explains that Paul came into a city dominated by gross immorality and commerce, where temple prostitutes were part of the religion. He notes Paul's many travels and problems, and says he is amazed Christianity ever survived. Les wonders why God did not put the gospel in the hands of angels or several hundred people instead of depending almost primarily on one man. He points out Paul was physically downtrodden, beaten, had physical problems, and was not a specimen of health, yet persevered and established churches everywhere, which brought Christianity to today.
