“Church involvement is absolutely critical for any healthy Christian life because it constitutes a basic reality check. Most Christians spend their weeks surrounded by people who are not Christians, being exposed to ideas, images, and values which are antithetical to Christianity which sell us myths as if they were reality, which teach us that madness is sanity and sanity is madness. Time spent with brothers and sisters in Christ on the Lord’s Day is thus time spent resetting your moral, spiritual, and intellectual bearings.
Whether you are a banker being tempted to greed by life during the week or a New Testament PhD student being bombarded with scholarship that mocks God’s word in the classroom from Monday to Friday, meeting with the people of God, singing his word, hearing his word read and preached and, indeed, meeting with the Triune in the awesome context of a worship service, is vital to your well-being.
You need to be there; and in nearly two decades of teaching, I have never yet met a student who messes up badly at an intellectual level who did not first mess up at an ecclesiastical level, whether through wrong choice of fellowship or no choice of fellowship at all. Put simply: if you are not involved in a church, then do not look for sympathy when your life leaves the rails and dives into a ditch.”
