I think David A. Bednar is trying to say that to become happy and reaming happy you have to be obedient. Being obedient is the key to being happy and having a wonderful life. if you were to do the opposite which is to be disobedient then you will live a life of misery and have a bad life so being obedient is the way to bring happiness.
