Bethany Verrett 30 Dec Adam and Eve were created in Paradise, but had to give birth to and raise their children in a broken world. Two of their children, Cain and Abel, became the quintessential story of jealousy and filial rivalry. Cain struck Abel down in anger, killing him. God sent Cain away, and into the world. In fear, Cain lamented he would be murdered, paid back in kind for his own actions. To prevent others from carrying out revenge, the Bible says that God marked Cain, a sign of His protection. Many seek to know the specifics about it, even though the Bible is vague. False theories have led to dangerous and even un-Biblical theories.
