One of the passions for some people in congregations is the desire to reactivate inactive or former members of the church. They believe if these people would reactivate the congregation would soar. This approach presents several challenges that diminish its effectiveness.
First, it only works a small percentage of the time. Second, the effort required to reactivate inactive people is often greater than the effort to reach new people. Third, those who became inactive did so for a specific reason that may not have been resolved. Reconciliation with the church needs to take place before or as these people return.
