I think you need to look a little more deeply into what Paul (and Moses before him) was actually saying instead of simply taking as true what someone says the verses are saying. The problem with most generic non-denominational churches today is that their theology is very superficial, and their worship heavy on emotion and psychological stimulus, and the practical result of their Bible interpretation is to read into the text what they feel it is saying to them rather than take it at face value in its historical context as speaking eternal, unchanging truth to fickle, prideful, self-absorbed, self-deluded sinners ... as it has been doing these many, many, many centuries as trends and fashions shifted and changed and whole nations and peoples rose and flourished and then foundered and disappeared.
Of course, light bulbs and guitars are not anti-God, neither are candles and organs. “Do not be deceived, my beloved brethren. Every good gift and every perfect gift is from above, and comes down from the Father of lights, with whom there is no variation or shadow of turning.” (James 1:16-17) Nothing God gives - and remember He is the Creator and Provider of all things - is anything less than good. It is man, in his sin and pride, who is able to turn any and every good gift of His to vain or even evil purpose.
My point is simply this: Where and when is entertainment ever appropriate in the presence of God? Show me any place in Scripture where this is either recommended or done with God’s approval. I look forward to your answer.
You just proved my point. “their theology is superficial”. That is the exact requirement I mentioned that would cause a church to be immature.

What it comes down to is YOUR opinion of entertainment. Some people view the piano as entertainment. Some view the organ as entertainment. Some view lights as entertainment. Some view guitars as entertainment.
