What does Genesis 2:1 mean?
The first verse of Genesis 2 begins with the term "thus," or, "so." This reflects back to the content of the prior passage, so this verse summarizes all of chapter 1. It is a statement of conclusion: God completed His work of creation. The heavens and the earth and every aspect of God's great creation was finished.Chapter and verse divisions were not part of the original Bible text; these words are meant to be read in a natural flow from those at the end of chapter 1. In Genesis 1:31, God declared all He had made as "very good." He accomplished exactly what He set out to do, and He was satisfied with the results. In this moment, nothing existed in creation which was bad, or corrupt, or out of sync with the plan and purpose of God. The heavens and earth were vast, teeming with life, and they were exactly as God intended them to be.
What will change this ideal state is human sin, as described in chapter 3.
