“Public confidence in the integrity of the Government is indispensable to faith in democracy; and when we lose faith in the system, we have lost faith in everything we fight and spend for.”

(A.J. Broomhall. Hudson Taylor and China’s Open Century, Book Five: Refiner’s Fire. London: Hodder and Stoughton and Overseas Missionary Fellowship, 1985, 407).

October 13, 2019 What keeps the months-long, massive Hong Kong protests going? https://www.cbsnews.com/news/hong-kong-protests-60-minutes-on-the-streets-of-hong-kong-with-pro-democracy-demonstrators-2019-10-13/?ftag=CNM-00-10aab7d&linkId=75253573

Please Use Your Liberty to Promote Ours (1997)
Context: We have faith in the power to change what needs to be changed but we are under no illusion that the transition from dictatorship to liberal democracy will be easy, or that democratic government will mean the end of all our problems. We know that our greatest challenges lie ahead of us and that our struggle to establish a stable, democratic society will continue beyond our own life span.
But we know that we are not alone. The cause of liberty and justice finds sympathetic responses around the world. Thinking and feeling people everywhere, regardless of color or creed, understand the deeply rooted human need for a meaningful existence that goes beyond the mere gratification of material desires. Those fortunate enough to live in societies where they are entitled to full political rights can reach out to help their less fortunate brethren in other areas of our troubled planet.

(zh-CN) 我们应当相信群众，我们应当相信党，这是两条根本的原理。如果怀疑这两条原理，那就什么事情也做不成了。
