Question: "What is the definition of evil?"
Answer: A dictionary definition of evil is “morally reprehensible, sinful, wicked.” The definition of evil in the Bible falls into two categories: evil against one another (murder, theft, adultery) and evil against God (unbelief, idolatry, blasphemy). From the prohibition against eating from the tree of the knowledge of good and evil in the Garden of Eden (Genesis 2:9), to the destruction of Babylon the Great (Revelation 18:2), the Bible speaks of evil.
For many centuries Christians have struggled with both the existence and the nature of evil. Most people would acknowledge that evil is real and has always had devastating effects on our world. From the sexual abuse of children to the horrific terrorist attacks on 9/11, evil continues to rear its ugly head in our own time. Many people are left wondering what exactly is evil and why does it exist.
The existence of evil has been used as a weapon by opponents of theism—and Christian theism in particular—for some time. The so-called “problem of evil” has been the subject of various arguments by atheists in an attempt to demonstrate that a God who is good simply cannot exist. By implying that God must be the creator of evil, God’s holy character has been called into question. There have been many arguments used to indict God as the cause of evil. Here is one of them:
1) God is the creator of everything that exists.
2) Evil exists.
3) Therefore, God is the creator of evil.
The logic of this syllogism is sound. The conclusion follows logically from the premises. But does this syllogism demonstrate that God is the creator of evil? The problem with this argument is its second premise, that evil is something. For evil is not a thing; it is a lack or privation of a good thing that God made. As Christian philosopher J. P. Moreland has noted, “Evil is a lack of goodness. It is goodness spoiled. You can have good without evil, but you cannot have evil without good.”
Goodness has existed as an attribute of God from all eternity. While God is perfectly holy and just, He is also perfectly good. Just as God has always existed, so too has goodness as it is a facet of God’s holy character. The same cannot be said for evil. Evil came into being with the rebellion of Satan and subsequently entered the physical universe with the fall of Adam. As Christian apologist Greg Koukl has said, “Human freedom was used in such a way as to diminish goodness in the world, and that diminution, that lack of goodness, that is what we call evil.” When God created Adam, He created him good, and He also created him free.
However, in creating Adam free, God indirectly created the possibility of evil, while not creating evil itself. When Adam chose to disobey God, he made this possibility a reality. The same scenario had previously played out when Satan fell by failing to serve and obey God. So it turns out that evil is not a direct creation of God; rather, evil is the result of persons (both angelic and human) exercising their freedom wrongly.
While evil is certainly real, it is important to recognize that evil does not have existence in and of itself. Rather, it only exists as a privation (or a parasite) on the good. It exists in the same way that a wound exists on an arm or as rust exists on a car. The rust cannot exist on its own any more than cold can exist without the existence of heat or darkness can exist without the existence of light.
Despite the horrible effects of evil on our world, the Christian believer can take comfort in the words of the Lord Jesus Christ recorded for us in the Gospel of John, “I have told you these things, so that in me you may have peace. In this world you will have trouble. But take heart! I have overcome the world” (John 16:33). More importantly, we look forward with great anticipation to our home in heaven where the ultimate evil, death, will finally be destroyed along with the “mourning, crying and pain” which it inevitably produces (Revelation 21:4).
