People test their grounds to see how much they can get away with or maybe once they reach a certain level of popularity they might want to see how much would be tolerable by their followers.
But I agree, churches should be moved by the spirit and not be tainted by flashy worldly things like videos, Facebook, youtube, phones/tablets, projectors etc.
I’ve been to churches were everything was programmed and it didn’t feel real.
What ppl don’t realize is that for them, there are always incentives and there aren’t always to glorify GOD but themselves and those around them.
They might think that is approved by God just because what they do might influenced by Christianity standards.
The fact is that no one truly knows whether God approves it unless the holy spirit tells you.
Otherwise you are been driven by your own notions not GOD’S will.
