Doctrine and Covenants 107:30-31

30 The decisions of these quorums, or either of them, are to be made in all righteousness, in holiness, and lowliness of heart, meekness and long-suffering, and in faith, and virtue, and knowledge, temperance, patience, godliness, brotherly kindness and charity;

31 Because the promise is, if these things abound in them they shall not be unfruitful in the knowledge of the Lord.
