Just a few years ago, the town of Manchester, Ky., was torn apart by drugs and corruption. But residents have since experienced revival.

Thousands of people marched through the streets of Manchester in May 2004, telling drug dealers to "get saved or get busted."

Doug Abner, pastor of Community Church in Manchester, said when the city prayed and asked God to forgive them for letting the enemy take over their town, God's presence showed up in a powerful way.

"First of all, when 63 churches in a small county marched through town together, for us, that was bigger than the parting of the Red Sea," he said.

"And you can talk to the 3,500 or 4,000 people that were there and everybody tears up," Abner recalled. "It was just an awesome thing that happened, and then from that -- all of a sudden the church had a voice in our community."
