People leave churches; it’s inevitable. They move from one church to another for a hundred different reasons, some good and some bad. Every pastor has experienced this, and more often than not it is disappointing or even painful.
Some people do it kindly and with clear communication about their reasons. Others disappear without a word, never to be seen or heard from again.
Despite knowing what you ought to think and feel toward people who leave your church, you are likely tempted toward some unhelpful responses.
