There is a great battle going on between good and evil. Every human being is a part of it, whether we want to be or not. Those who are good want to obey God, and those who do evil follow Satan. But it wasn’t always that way. Long ago in heaven there was only happiness and harmony. Every creature throughout the entire universe adored God and worshipped Him as the Creator. No one imagined that evil could find a home in God’s universe, because everything was perfect and filled with peace and love.
