Read Genesis 1 - 3. Many people often claim that God does not exist because evil exist in the World. Genesis 1 & 2 tells us that the World was perfect. Everything was good and perfect. Man was made in the image of God and had direct fellowship with God. There was no evil in the world at all.

But after man rejected God, evil was introduced into the world. The term of "evil" really means of rejecting God's authority and focusing on yourself. We can contribute evil as murder and rape. But what about lusting, lying, stealing, and coveting? You see, all of these are evil in the sight of a Holy God.

Can God put an end to all of the evil in the World? Sure, He can, but He would have to wipe out all of humanity to do so. You see, man is not just in darkness; but rather he is darkness. If God were to cleanse the world from evil at 12:00, where would you be at 12:01?
