For any rational being, these are good and obvious questions to justify the existence of God who we say is full of mercy, love and care. From my little expositions, I have established that there were other spirits apart from God, these are lesser spirits and God remains the King of all the spirits. Some of these lesser spirits are spirits of darkness and they enjoy the pain of man as God created man in his own image and gave him dominion over all things created. Therefore, the envy of man started from creation, the lesser spirits have been subjecting man to all disasters, pain and death. In fact, there is a spirit of death which is one of the lesser spirits which kills the physical body but not the soul.( Hebrews 2:14).
