Ever been criticized in your worship ministry before?
It was probably something super petty. Someone didn't like the shirt you wore on Sunday…
Unfortunately, when it comes to worship ministry, criticism is just part of the territory. Everyone has different ideas about what should be done and, therefore, you can't please everyone. So, you might do something that some people really like and others don't. That's just how it is operating in a church with imperfect people (by the way, you're imperfect too!)
