The problem of evil in the world often raises many questions about God and whether he is actually omniscient, omni-benevolent, and omnipotent. If God is so good, how can his world be so bad? Many people have even deserted their faith because of the problem of evil. Take September 11 as an example. How could God let more than 3,000 innocent souls die if he is so divine? "The word 'theodicy', comes from the Greek words 'theos' (God) and 'dike' (justice), is a word used in Christian theology to show that God is righteous and just despite the presence of evil in the world." .
I feel that God gave humans the choice to make their own decisions and to have free-will. Therefore, he is not responsible for both moral and natural evil that occurs because of our independent choices. The existence of evil is rationally incompatible with the existence of a "good god", therefore an outside force must be involved, which is called free-will. The actions of free-will led to two kinds of evil in the world; moral and natural. Natural evil consists of events that take place and cause suffering, such as diseases and natural disasters. Moral evil consists of the actions that people make from their own personal judgement and/or behavior, such as murder or stealing. Evil is a choice that people make.
According to the Bible, in the book of Genesis 3:1-24, God gave humans a choice as to whether they would obey or disobey him and to make their own decisions. After the creation of the first man and woman, God gave them the ability to exercise free-will in the story that took place in the Garden of Eden. God told Adam and Eve not to eat from the tree of the knowledge of good and evil, yet they were tempted by the serpent to disobey God and as a result they ate the forbidden fruit. So the Lord God said, "The man has now become like one of us, knowing good and evil. He must not be allowed to reach out his hand and take also from the tree of life and eat, and live forever.
