One of the challenges atheists frequently raise to belief in God is the question of evil. The argument is that if God exists and if God is good and all-powerful, why does evil exist? If there is evil, according to the atheist view, then that God does not exist. The truth is that the existence of evil challenges atheism.
The presence of evil is a bigger problem for atheists than it is for Christians. From a Christian perspective, evil is a product of the rejection of God. The Bible portrays human existence is as a battleground between good and evil, between God and the forces of Satan. The book of Job is the clearest example, but the Bible covers this theme again and again.
The existence of evil challenges atheism as the famous philosopher Alan Plantinga describes:
“Could there really be any such thing as horrifying wickedness if there were no God and we just evolved? I don’t see how. There can be such a thing only if there is a way that rational creatures are supposed to live, obliged to live… A secular way of looking at the world has no place for genuine moral obligation of any sort … and thus no way there is such a thing as genuine and appalling wickedness. Accordingly, if you think there really is such a thing as horrifying wickedness and not just an illusion of some sort, then you have a powerful argument for the reality of God.” (From Timothy Keller’s book The Reason for God pages 26-27)
Atheism has no way of giving a purpose for human existence. That leads atheists like Richard Dawkins to maintain that there is no such thing as good or evil (see Dawkin’s book River Out of Eden, page 133). If an atheist rationally believes that evil does not exist, they negate their challenge to belief in God. Therefore, the existence of evil challenges atheism.
