Striving for doing things well (quality) is neither good or bad, but it can be done for good or bad reasons.
It’s not good to make things quality for quality’s sake. Neither to make you look impressive, or to make other people feel ashamed in comparison.
But it is good to do things quality because you love the people you’re doing it for. Quality, well rehearsed plans, and beauty are all ways of loving people. A quality sound system makes it easy to hear the speaker and avoids the ear-curdling squeaks. A quality welcoming process will always miss some people, but it will always help more people than a shoddy system.
Yes, some Christians and churches just seem to want to do things because they look cool. But maybe they’re not as shallow as you assume, maybe they just have a greater love for people than you’re aware of.
