Genesis 4:17-5:32 tells us the story of two families, the descendants of Cain and the descendants of Seth. The family of Cain are the offspring of the serpent and the family of Seth are the offspring of Eve. Genesis 3:15 tells us that through Eve’s offspring, Seth’s line, will come a savior who will defeat sin, evil, and the family of the serpent. This new family comes to completion in Jesus Christ. We join the family of God through faith in the Son of God.
