Without too much of a mental jump, there's a spiritual application here. I've often heard people who have been saved for a while wonder aloud why they needed to be in church. Their "spiritual house" is in order but there is stuff that can't be seen. But we, as Christians, often pack away a bunch of stuff where it can't be seen. Sometimes, its really good stuff but we've forgotten about it or can't seem to access it. Sometimes, it's stuff that needs to be thrown out—garbage. A lot of times, its stuff that we need to share with others.
Church is the best place for going through those "boxes of spiritual stuff." Maybe something will be said in a sermon that leads to a box. Maybe the sight of a need in another member of the body will unpack something you need to share.
You need to be in church so you don't become a spiritual hoarder.
