The music and the preaching and the teaching don't have to be perfect either. I like to say you don't have to be Chuck Swindoll to grow a class. But people do want to experience God. People need to experience God when we teach, when we sing, and when we pray. It is not even enough that people sense God's presence when they come to church.
People hunger for love.
If we want to change from a Teflon church to a Velcro church, we must love people. They hunger for us to open our homes and have them in and eat with them and play with them and enjoy life with them. They want to experience God's presence in our worship services, God's truth in our teaching and God's love in our fellowship. Good fishermen know that they key to fishing is understanding the fish. Understanding where they eat, what they eat, and when they eat.
