An Exciting Example of Spiritual Renewal

This is narrative (in Tim Keller's Prayer Study Guide) I read about a spiritual renewal movement in Korea:

In 1903 in the city of Wonsan, there was a Canadian missionary, R. A. Hardie, who was studying prayer. He came upon Luke 11:13: “If you then, though you are evil, know how to give good gifts to your children, how much more will your Father in heaven give the Holy Spirit to those who ask him!” He was deeply convicted that his missionary work had been motivated by a desire to prove himself to others and God; that he had not based it on grace, prayer, and the Holy Spirit.. He gave this testimony to a Korean congregation, publicly repenting of his pride, hardness of heart, and lack of faith in Christ. This was electrifying in a largely Confucian culture where losing face was considered unthinkable. The people began to repent, pray, and seek the Holy Spirit in their midst. Awakening spread in and around the region of Wonsan and the churches began to grow.
At a Bible conference meeting on January 17, 1907 in the city of Pyongyang, a huge crowd gathered. The preacher concluded the sermon and called for prayer, encouraging them to pray aloud. The whole audience began to pray out loud and in unison. Suddenly they burst into a roar of prayer as people were feeling a strong urge to prayer. William Blair, a Presbyterian missionary, was present and later described the scene:
“The whole audience would break out into audible prayer, and the effect of that audience of hundreds of men praying together in audible prayer was something indescribable. Again, after another confession, they would break out into uncontrollable weeping and we would all weep together. We couldn't’t help it. And so the meeting went on until 2 a.m., with confession and weeping and praying. …We had prayed to God for an outpouring of His Holy Spirit upon the people and it had come.
William Blair says that after the week was over:
All through the city people were going from house to house, confessing wrongs, returning stolen property, not only to Christians but to heathens. A Chinese merchant was astounded to have a Christian walk in and pay him a large sum of money he had obtained unjustly years before. The whole city was stirred.
Harvie Conn, a missionary to Korea for many years, writes that
Confucianism made an idol out of hierarchical authority and was therefore deeply self-righteous. This led to the belief that no one of any real stature should repent. It represented a loss of face. But the gospel brought about a power encounter with the self-righteousness of the Confucian world-view at the heart of Korean culture. A new concept of humility and greatness in the gospel brought about an enormous shift in the lives of converts. In the revival, males especially, who had next to no ability to deal with shame and failure, experienced the love of God in the gospel through the Holy Spirit. It freed them to admit their flaws.
