Happiness is a condition of the soul. This joyous state comes as a result of righteous living.
Life is good, when you live in such a way to make it so
It does not matter the circumstances, trials, or challenges that might surround us; an understanding of the doctrine of Christ and His Atonement will be the source of our strength and peace-yes, brothers and sisters, that internal tranquility that is born of the Spirit and which the Lord gives to His faithful Saints.
This promise from the Lord to His Saints does not imply that we will be exempt from sufferings or trials but that we will be sustained through them and that we will know that it is the Lord who has sustained us.
Believing, desiring, deciding, and choosing correctly are the simple actions that define an increase in happiness and an increase in the inner assurance that transcends this life.
