In 1950, Indy car pit crews consisted of four men—including the driver! No one was allowed to get near the car except this small crew of specialists. A routine pit stop to replace two tires and fill the tank back then took more than 60 seconds. Today, a crew consists of 11 members—excluding the driver. Six are permitted direct contact with the car. Five serve as behind-the-wall assistants. A full service pit stop that replaces all four tires, adjusts the wings, and tops off the tank now takes less than eight seconds! Formula 1 pit crews are even bigger—sometimes involving over 20 people who all have their role to play. When everyone understands his role, and when everyone on the pit crew does his job with purpose and passion, the team can complete the same job in under three seconds.

When the work of the church is carried out by a small handful of people, including the pastor, progress is slow and sometimes awkward. But when every member knows and fills his or her role, the difference can be amazing to behold.
