It's fascinating to read how the New Testament authors describe church life. Almost everything they write has to do directly with interpersonal relationships. All of the "one another" exhortations are examples of this. If we studied the application passages of Paul's letters we'd see a comprehensive focus upon relationships between brothers and sisters in Christ.
What we don't see too much of is a focus on events. Although we read a few descriptions of church gatherings (for example Acts 20), these are not many. A significant passage such as Hebrews 10:24-25 focuses much more on the relationships involved than on the specifics of the meetings themselves.
In our culture the focus of the church seems to lean toward events. This can be true whether talking about more institutional churches or simpler ones. Although this is done with good intentions, it indicates priorities that are at least somewhat off target.
We'd all do well to ask whether or not we are more focused on relationships or events. I admit that there is almost always overlap between relationships with friends and events we are all involved in. However, they are not the same thing. Which of the two do we spend more time on? Do we put more work into events or relationships?
When we read the New Testament, we see Christians who had some great relationships and some that weren't so great. The writers dealt much with these issues. That was their concern. The church today (that's all of us Christ-followers) benefits when we take a look both at our relationships and at how much effort we place into those relationships.
