What does Genesis 1:2 mean?
Genesis 1:1 announced that God created everything: "the heavens and the earth." Verse 2 begins to describe the process of that creation.According to this text, the earth was empty and literally in chaos. The Hebrew words used here are tōhu and bōhu, translated as "formless" and "void." Segments of Bible scholarship disagree about whether this "formlessness" was the state of the earth immediately after the initial creation, or the result of some events between Genesis 1:1 and Genesis 1:2. In either case, at this point in the story, the earth is covered with deep waters. A darkness was over the surface, and the Spirit of God was over the waters.
Why darkness? Light will not be created until the following verse. There can be only darkness at this point. Still, God's Spirit is moving in this darkness. God is preparing to speak, to act with great power to bring order and light to this chaos.
