I have been a pastor for a long time. One of the things I have found to be true as a follower of Jesus is this: those of us who choose to actively engage with Him together with others in a healthy local church have a much more enjoyable, productive, adventure-filled, "challenged-to-go-beyond our-comfort-zone" life than those who try to go it alone. (*I don't have time to define "healthy" here, but can recommend a great book if you would like to go deeper. It is "Life Together" by Bonhoeffer. Pay particular attention to Chapter 1 entitled "Community".)
And as a pastor, I have also found something else to be true: it is really hard to continue to be actively involved in a local church! This has always been the case...ever since Jesus called 12 disciples together to form the first Church. Why is it so? While there are many, many reasons, I will mention only two: 1. Wherever there are people, there will be conflict, and, 2. Wherever there are Christians, there will be people with unrealistic expectations placed upon other people...I would suggest greater expectations than they place on their work or school associates, and sometimes more than their own family members.
