True to the Faith, (2004), 84

The thirteenth article of faith states, “We believe in being honest.” To be honest means to be sincere, truthful, and without deceit at all times.

When you are honest in every way, you are able to enjoy peace of mind and maintain self-respect. You build strength of character, which allows you to be of service to God and others. You are trustworthy in the eyes of God and those around you.

On the other hand, if you are dishonest in your words or actions, you hurt yourself and often hurt others as well. If you lie, steal, cheat, or neglect to give the full amount of work for your pay, you lose your self-respect. You lose the guidance of the Holy Ghost. You may find that you have damaged relationships with family members and friends and that people no longer trust you.

Being honest often requires courage and sacrifice, especially when others try to persuade you to justify dishonest behavior. If you find yourself in such a situation, remember that the lasting peace that comes from being honest is more valuable than the momentary relief of following the crowd.
