For most Christians, “church” is the big box where they attend a “service” on Sunday mornings.
If they are super-committed Christians, maybe it means attending additional meetings and programs that emanate from the Box during the rest of the week.

Outside the Box!
It took me years to learn to think – and act – outside that box!
Yes, Christ can be found in the box. But He does His best work, I’ve found, apart from and outside the box.
My spiritual heritage was outside the box. I was birthed into the Kingdom of God during the Jesus Movement and was very active in what we’d now call a network of “organic” or “simple” fellowships. But as the decades passed, I allowed myself to be slowly but surely drawn into the box.
Getting back out required a fundamental paradigm shift as I honestly and painfully let Scripture strip away my man-made traditions and accumulated expectations.
