A church that recognizes the depth of its sin is a church that is wading into the deep end of the Gospel of grace.
I love my church and I love gathering with God's people to worship together in our particular church. However, I also love the opportunity that vacations afford for visiting other churches. Observing how they worship, experiencing church as a visitor, sitting under someone else's preaching, and not thinking about a service that I am responsible for has, many times, challenged, encouraged, and even refreshed me.
