Elder Douglas discussed how the formation of hurricanes is governed by physical laws: the ocean water MUST be at least 80 degrees for at least 165 feet below the ocean’s surface and there must be winds that cause the water to vaporize, clouds that form, and the wind must continue blowing to create a spiral pattern over the ocean.
Similarly, he said, our happiness is governed by a spiritual law.
What is that law? It’s really quite simple. Happiness comes from keeping the commandments.
