To ADMINISTER is to perform the ordinances of the gospel. It is an act of service to either an individual or a collective group of people.
For example, deacons, teachers and priests who are authorised, administer the Lord's sacrament to the congregation each Sunday. Fathers can administer to members of their family by giving priesthood blessings when needed. Ministers assigned to watch over individuals in the church can also provide blessings of comfort and offer special prayers of healing by the laying on of hands. Temple patrons administer the sacred ordinances of the gospel to both the living, and by the living on behalf of the dead.
Administering also implies giving all kinds of healing and comfort in spiritual, mental and emotional matters.
Be sensitive to the needs of those you minister to and be ready to administer to them when in need.
