This document discusses strategies for urban evangelism and the role of medical missionary work. It provides 3 key points:
1. Medical missionary work is an essential part of gospel ministry that involves healing, preaching, and helping the poor and oppressed. Every church should engage in training members in medical missionary work and health reform.
2. Reaching cities requires organized teams of trained workers using various approaches tailored to different groups. Methods may change over time under God's guidance.
3. The gospel spreads most effectively through social networks as believers share their faith with friends, families, and communities through both words and acts of service. Viral spread through online tools can also help the message increase rapidly.
