When they launch the Space Shuttle from Cape Canaveral they strap it to a booster that contains five million gallons of liquid fuel which all burns off in 8.5 minutes. Then the shuttle travels another four million miles on a little bucket of fuel. The maximum amount of energy required in nature is the amount needed to begin a stationary object in motion. It takes a lot of energy to overcome inertia. One of the great problems of recent years has been how to bring the stadium-scale momentum created by a PK event back into the local church.
Variety here is key.
The secret is to have many different kinds of events to create momentum that appeal to the interests of men on the fringe. If you are trying to reach men on the fringe, don't sing praise music at every men's event you have. Tailor some of the events so that they will feel as comfortable as possible. Also, you may not want to have a strong evangelistic appeal at every event. Sometimes, men on the fringe just need the opportunity to build relationships with men in the church.
