Cities have been around since the Old Testament was penned. In Jonah, we read that God declared: "Should I not care about the great city of Nineveh, which has more than 120,000 people who cannot distinguish between their right and their left, as well as many animals?" (Jonah 4:11) Today, the majority of the world's population live in mega-cities; cities with a lot more than the 120,000 people of Ninevah. If you think God doesn't care about the condition of our world's cities, think again! God cares deeply, and He desires His church to GO to the cities and fulfill the Great Commission there. Sadly, many churches have left the inner cities to go out to the suburbs, where it is seemingly safe and comfortable. It is time for the church to get serious about impacting the mega-cities for Christ. The city is where Jesus would be. As His followers, we must go to them or risk disobedience, as Jonah demonstrated in his unwillingness to GO. We must plant our lives and God's church firmly in the cities and we must do it now! Don Overstreet has planted more than 500 churches in his 50+ years in ministry. This book will motivate you to search your heart for how God might want you to move into city mission work.
