What does an elder do?

The New Testament writers often referred to "elders" or "deacons" when referring to local churches.  

The elders are primarily concerned with the spiritual, emotional, and physical health of the Christians under their care. Working together with the minister, church staff, and deacons, these men and their spouses seek to nurture the growth and well-being of the Christians in their local church.

Their primary concern is for PEOPLE, not programs or budgets. That's why the New Testament refers to elders as "shepherds."  Elders serve as mentors, teachers, and enablers to help each Christian under their care grow up into the fullness of Christ (Eph 4:11-13).
