“The covenants we make with God involve promises to do, not merely to refrain from doing, to work righteousness as well as to avoid evil. The children of Israel made such covenants through Moses . . . though hardly was Moses’ back turned until they had broken their promise through wrongdoing. In the baptismal waters we give a similar undertaking and we repledge it in the ordinance of the sacrament. Not to honor these pledges, to refuse to serve or to accept responsibility and do less than one’s best at it, is a sin of omission” (Teachings of Presidents of the Church: Spencer W. Kimball, p. 127).
