I met a famous Christian musician many years ago. I asked him if he played in a Church band...He laughed and said "NO".
It took me a few years to figure out why. Now I totally understand. The better you get and the more dedicated you are the harder it is to put up with Church politics and lazy musicians.
You really do have to lower your musical dedication and ambition to put up with what normally happens when working with volunteer unprofessional musicians. Spoon feeding some of these people just to get them to tune their instruments or learn a scale or complex chord. Some times they don't even show up with their instruments???
