Last Sunday, we had a very complicated service -- lots of different cues, video clips interspersed with short dramas, sound effects, and a large cast of participants. Because we were working with a few new crew members and guest performers from children's ministry, we allowed some extra time to practice the run, over and above our normal routine.
The first time through, things were pretty ragged. Mistakes were being made; communication was breaking down. What was supposed to be a 20-minute run-through had taken over 35 minutes. There was plenty of opportunity for conflict, but fortunately, the folks involved are patient, genial types, and familiar with the challenges of production. We all took a deep breath, reset, and started again. The second run-through was much improved, and though there were still a few mistakes, we were out of time. Our folks huddled over a few details, said a prayer, and went to our stations, prepped and ready.
The resulting service was virtually flawless, and the response was great. The experience was a great reminder of why we rehearse. Not only was our congregation impacted by a quality production, but our team was able to rise to the occasion together, and enjoy a tangible win.
I've been in other settings (schools, corporate events, and especially churches) where excellence was a low-priority, and time to rehearse was deemed unimportant. All too often, people shed rehearsal time for the sake of "spontaneity" or "to allow the spirit to move" and, sadly, the results are usually sloppy and embarrassing.

Recently, I saw an interview with musician and producer Quincy Jones, where he defended the rigors of planning, discipline, and rehearsal. The interviewer was taken aback, surprised that the legendary jazz artist would put such value on structure:
How can you improvise under such strict conditions? Jones' wonderful explanation underscored just how important planning can be: "You've got to do all the detail work, the planning and rehearsal, so that when it's time for the performance, you can just relax, shut off your brain, and let your soul take over. The planning paves the way for the magic."
