What is the Origin of Evil? Where did Evil Come From?
In order for us to discuss the origin of evil, we must first define it. Biblically speaking, evil is that which is contrary to the character and will of God. It is the opposite of what is good. Evil is an issue of morality and intention. A rock is not evil but using a rock to murder someone is evil. Evil is committed by people and fallen angels. Evil is first mentioned in Genesis 2:9, “Out of the ground the LORD God caused to grow every tree that is pleasing to the sight and good for food; the tree of life also in the midst of the garden, and the tree of the knowledge of good and evil.” In this verse, evil is contrasted with good. The Hebrew word for evil is רַע, rah, which occurs 664 times in the Old Testament and is translated as evil, wickedness, disaster, harm, bad, fierce, downcast, ugly, etc.
In the New Testament, the first occurrence of the word evil is Matthew 5:11, “Blessed are you when people insult you and persecute you, and falsely say all kinds of evil against you because of Me.” The Greek word is πονηρός, ponaros, which occurs 77 times. The Greek word is translated as evil, bad, wicked, envious, worthless, etc. So, again, evil is that which is contrary to the will and character of God and is synonymous with wickedness, worthlessness, disaster, moral degradation, etc.." from the article: What is the origin of evil?
