In Genesis 4, man’s rejection of God and the curses that follow are fully displayed in the story of one brother murdering another brother because of jealousy. Cain did not heed the warning, “The LORD said to Cain, ‘Why are you angry, and why has your face fallen? 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 contrary to you, but you must rule over it.’” Genesis 4:6–7.
The list at the end of the chapter shows that Cain’s descendants intensify and multiply the rebellion, anger, and hatred that entered our world when sin corrupted all that God had made. How tragic to see man’s broken relationship with God that resulted in such broken relationships with each other.
There is hope, though. We are told that another brother, Seth, is born in place of the murdered Abel. It is then when we read these beautiful words, “At that time people began to call upon the name of the LORD.” May we call upon His name today!
