Read Genesis 4:20-22
Immediately after the story of Cain murdering Abel, we find a long geneology. We do not know all the people who are listed, but we do learn some important things.
We see that God continues to work through human history. Generation after generation the world is unfolding. Families and nations are developing. And at the end of chapter 4, we learn that the worship of God is occurring. The Fall has not destroyed God’s ability to work in and through us.
When I read this section of the Bible, I always think to myself, “What God can do through sinful people remains amazing. Imagine what God might have been able to do if we had not fallen.”
