Paul Tripp describes how pastors come to live the spiritual lives that pastors tell everyone else they should not live.
…it is my grief to say that individualized, privatized Christianity still lives. Sadly, it lives in the lives and ministries of many pastors who have forged or been allowed to forge a life that is live above or outside of the body of Christ. It happens this way for many pastors. Their spiritual life became immediately more privatized when they left their home church to go to seminary in another city. For many, the seminary became their primary spiritual community, a community that was neither personal nor pastoral in the way it handled Scripture and related to the student. Having graduated from an environment where, for three or more years, they were not pastored and had a rather casual relationship to a local church , they are now called by a church that doesn’t really know them. This is all magnified by the fact that they are not joining the church per se; no, they have been called to lead it. So they are not entering into a situation of naturally expected peer, mutual-ministry relationships. The are not afforded the normal expectations and protections that anyone else is offered when they join the church. It is a potentially unbiblical and unhealthy culture that does not protect the pastor and does not guard his ministry from danger.
