This is a major issue for evangelical ministry, longevity in one place. Great article below:
The structure of our training effectively forces ministers into at least a decade of moving and moving again. This is wrong for people so committed to the importance of good relationships. There is a real danger that ministers disconnect from the very people they should be connecting with – in the church and the parish. Like military families, it ends up being easier to just have deep relationships with other military families that understand the strange lifestyle.
