Meeting for worship
It should be the care of elders to foster the spiritual life of all members and to give caution and advice to Friends who share in the vocal ministry. They should look out for Friends who may be likely to help the ministry and lead them to make their right contribution to the life of their meeting, and to encourage our members to think deeply on the great issues and problems of life and the fundamentals of our faith.
This, however, is not the duty of elders alone; as any Friends may hinder the work of the ministry by a critical or unloving spirit, so their sympathy and prayers for those who speak will help to create an atmosphere in which an inspired and inspiring ministry may grow. A friendly word of thankfulness from one who has been helped is often a great source of encouragement to the minister.
