Even better, teach all members about gifts and collect profiles of every member. This may take time but is worth it in the long run. Create an atmosphere of gifts-based ministry in your church. Rather than power, tenure, or position determining people's placement, set a new standard. Match members to ministries according to gifts.
Spiritual maturity is an important factor as well for leadership positions.
Determine active membership. Keep this list before the committee and insure that all are asked to do some part in the church. Invite leaders to participate in the building of ministry teams. Have them make suggestions. Allow them to make phone calls.
