"The Not Even Once Club" is a book that encourages children to promise they will never sin, "Not. Even. Once." It endorses giving children candy as a reward for righteous behavior and withholding candy and group membership for children who sin even once. This book does not mention Christ, the Atonement, or repentance---except in a tiny section of the parents' guide.
We urge Deseret Book to prayerfully consider the spiritual and psychological damage caused to children by leading them to believe they can live a perfectly sinless life without a single mistake, a standard so impossible that only Jesus Christ achieved it.
"If we say that we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness." 1 John 1:8-9
