Basic model for leadership selection

Chapter 34 of Elders and Leaders presents a basic model for leadership selection. No mention of “calling” is found in this section. The absence of this concept is not surprising when realizing that in regard to the office of elder/overseer Getz earlier wrote, “First, Paul implied that any Christian man could seek this role. There was no special, divine calling associated with this task” (96).
Do you believe that Getz is correct? Should a “calling” be on someone’s life to serve in the
office of elder/overseer as a church revitalizer? Present an argument from Scripture. You may
use personal examples and experience; however, the core argument needs to be grounded in
the context of Scripture.
