Cain and Abel are Bible characters who teach us about the compounding nature of envy, which moves to hate, which moved to murder in our scripture reading for today. The Bible says not to allow a “root of bitterness” to take hold in your life (Hebrews 12:15), because it will grow and metastasize, and become fatal, both to you and others. The Bible illustrates this in Genesis 4, verses one through sixteen.
(Genesis 4:1-16) 1 Adam made love to his wife Eve, and she became pregnant and gave birth to Cain. She said, “With the help of the Lord I have brought forth a man.” 2 Later she gave birth to his brother Abel. Now Abel kept flocks, and Cain worked the soil. 3 In the course of time Cain brought some of the fruits of the soil as an offering to the Lord. 4 And Abel also brought an offering—fat portions from some of the firstborn of his flock. The Lord looked with favor on Abel and his offering, 5 but on Cain and his offering he did not look with favor. So Cain was very angry, and his face was downcast.
6 Then the Lord said to Cain, “Why are you angry? Why is your face downcast? 7 If you do what is right, will you not be accepted? But if you do not do what is right, sin is crouching at your door; it desires to have you, but you must rule over it.” 8 Now Cain said to his brother Abel, “Let’s go out to the field.”[d] While they were in the field, Cain attacked his brother Abel and killed him.
9 Then the Lord said to Cain, “Where is your brother Abel?” “I don’t know,” he replied. “Am I my brother’s keeper?” 10 The Lord said, “What have you done? Listen! Your brother’s blood cries out to me from the ground. 11 Now you are under a curse and driven from the ground, which opened its mouth to receive your brother’s blood from your hand. 12 When you work the ground, it will no longer yield its crops for you. You will be a restless wanderer on the earth.”
13 Cain said to the Lord, “My punishment is more than I can bear. 14 Today you are driving me from the land, and I will be hidden from your presence; I will be a restless wanderer on the earth, and whoever finds me will kill me.” 15 But the Lord said to him, “Not so[e]; anyone who kills Cain will suffer vengeance seven times over.” Then the Lord put a mark on Cain so that no one who found him would kill him. 16 So Cain went out from the Lord’s presence and lived in the land of Nod, east of Eden. (Genesis 4:1-16)
