The last time I was in a large church like this, it WAS a concert. Full band, lighting smoke machine, etc.
Not my scene. We have a home church group and we volunteer for some outreach programs.
They can keep the big, flashy Millennial church program. Heck, they even had a coffee/latte bar and barista in the lobby.
I visited a megachurch with a lobby set up to resemble like a mall. It had a coffee shop called “HeBrews.” I didn’t go back.
