"Our behavior in public must be above reproach. Our behavior in private is even more important. It must clear the standard set by the Lord. We cannot indulge in sin, let alone try to cover our sins. We cannot gratify our pride. We cannot partake of the vanity of unrighteous ambition. We cannot exercise control, or dominion, or compulsion upon our wives or children, or any others in any degree of unrighteousness.
"If we do any of these things, the powers of heaven are withdrawn. The Spirit of the Lord is grieved. The very virtue of our priesthood is nullified. Its authority is lost.
"The manner of our living, the words we speak, and our everyday behavior have a bearing upon our effectiveness as men and boys holding the priesthood."
- Pres. Gordon B. Hinckley, President of the Church, "Personal Worthiness to Exercise the Priesthood," Ensign, May 2002, p. 52
