"Now Adam knew Eve his wife, and she conceived and bore Cain, saying, "I have gotten a man with the help of the LORD." 2 And again, she bore his brother Abel. Now Abel was a keeper of sheep, and Cain a worker of the ground. 3 In the course of time Cain brought to the LORD an offering of the fruit of the ground, 4 and Abel also brought of the firstborn of his flock and of their fat portions. And the LORD had regard for Abel and his offering, 5 but for Cain and his offering he had no regard. So Cain was very angry, and his face fell. 6 The LORD said to Cain, "Why are you angry, and why has your face fallen? 7 If you do well, will you not be accepted? And if you do not do well, sin is crouching at the door. Its desire is for you, but you must rule over it." 8 Cain spoke to Abel his brother. And when they were in the field, Cain rose up against his brother Abel and killed him. 9 Then the LORD said to Cain, "Where is Abel your brother?" He said, "I do not know; am I my brother's keeper?" 10 And the LORD said, "What have you done? The voice of your brother's blood is crying to me from the ground. 11 And now you are cursed from the ground, which has opened its mouth to receive your brother's blood from your hand. 12 When you work the ground, it shall no longer yield to you its strength. You shall be a fugitive and a wanderer on the earth." 13 Cain said to the LORD, "My punishment is greater than I can bear. 14 Behold, you have driven me today away from the ground, and from your face I shall be hidden. I shall be a fugitive and a wanderer on the earth, and whoever finds me will kill me." 15 Then the LORD said to him, "Not so! If anyone kills Cain, vengeance shall be taken on him sevenfold." And the LORD put a mark on Cain, lest any who found him should attack him. 16 Then Cain went away from the presence of the LORD and settled in the land of Nod, east of Eden. 17 Cain knew his wife, and she conceived and bore Enoch. When he built a city, he called the name of the city after the name of his son, Enoch."
The above is an accurate historical account from near the beginning of the human race. The time period is about 100 A.C. (After Creation) or about 4100 B.C. By this time it is possible that there were about 4,000 people on the earth (Genesis 1:28, "Be fruitful and multiply...").
We read the account of two of the sons of Adam and Eve, Cain and Abel. Abel was a prophet of God (see Luke 11:49-51). Because sin had entered the world and without the shedding of blood there is no forgiveness of sin (Hebrews 9:22), God directed Abel to make a blood sacrifice and to instruct the people to make blood sacrifices (prophets deliver God's messages to His people).
Cain did not listen to Abel's message from God and offered a grain sacrifice. God was pleased with Abel's sacrifice, but had no regard for Cain's offering. Cain became very angry. God asked Cain why he was so angry and warned him of the danger of sin.
God told Cain he must not let sin rule his life (vs 7). However, Cain again did not listen to God and let sin rule. Cain devised a way to kill Abel.
God disciplined Cain for his sin (vs 10-16). Cain became a fugitive and wanderer on the earth away from the safety of his immediate family and the LORD (vs 16). Cain, knowing how sin had affected the 4,000+ people born to Adam and Eve who had left mother and father to start their own families feared for his life (vs 14). God protected Cain (vs 15). Cain and his wife, chosen from the many offspring of Adam and Eve and Adam and Eve's children, began a family and built a city named after his son, Enoch.
What lessons can we learn from this historical account of Cain and Abel?
It is very important for us to learn and live the Word of God, the Bible. Jesus tells us in Luke 11:28, "Blessed... are those who hear God's word and obey it."
