1. In God's image (1-17)

Genesis 5 starts again Adam's lineage through his son Seth. Adam's descendants through Seth were different from the descendants of Cain described in Genesis 4. Cain's descendants were corrupt and full of violence, but Seth's descendants called on the name of the Lord (4:24). God created mankind in his own image. Even though Adam sinned, the image of God was still there. People need their father God. Seth's descendants were mortal men. They were born, they had children, and they died. Their life spans were long, maybe because the fruit of sin had not taken its toll. They passed down their faith from generation to generation.

2. Enoch and Noah (18-32)

Enoch was in Seth's line. Hebrews 11:5,6 says that he was a man whose faith pleased God. He did not experience death; he walked with God, and God took him to heaven. Another Lamech is in Seth's line. He is quite different from the self-centered descendant of Cain. He feared God and overcame his despair, so he could name his son "Noah."
