Happiness

President Thomas S Monson, Obedience Brings Blessings, General Conference April 2013

“Throughout the ages, men and women have sought for knowledge and understanding concerning this mortal existence and their place and purpose in it, as well as for the way to peace and happiness. Such a search is undertaken by each of us.

This knowledge and understanding are available to all mankind. They are contained in truths which are eternal.”
...
"There are rules and laws to help ensure our physical safety. Likewise, the Lord has provided guidelines and commandments to help ensure our spiritual safety so that we might successfully navigate this often-treacherous mortal existence and return eventually to our Heavenly Father."

Mosiah 2:41 41 And moreover, I would desire that ye should consider on the blessed and happy state of those that keep the commandments of God. For behold, they are blessed in all things, both temporal and spiritual; and if they hold out faithful to the end they are received into heaven, that thereby they may dwell with God in a state of never-ending happiness. O remember, remember that these things are true; for the Lord God hath spoken it.

Jose L Alonso of the Seventy, Doing the Right Thing at the Right Time, without Delay, General Conference, October 2011

“Some have lost a sense of happiness and joy. The prophets have declared that true happiness is found in following the example and teachings of Christ. He is our Savior, He is our teacher, and He is the perfect example.”
