The letters to the seven churches are the only time that Jesus speaks directly to us, by Revelation. The gospels are all reports of what he said, by the apostles, but those seven letters are him speaking in person.
China could be the new throne. 300m to 400m people in the underground church – ignore wiki and other estimates – powered by Chinese Christians like Brother Yun, the heavenly man. They had to tell the American mission societies to stop sending missionaries, because nobody liked them. They would only preach for 40 minutes. “Unless they preach for at least two hours, people will not come”. Brother Yun’s son and Finnish mentor came to our daughter’s church, a truly humbling experience because, unlike most missionaries, they hadn’t come to raise money; they’d come in the hope that we could learn from their techniques, and be involved in being so effective in spreading the word. Zero to 300m in 20 years. In China!
