Genesis 1:5 and 1:8 provide essential insights into God’s authority, not only as the Maker of the world but also as the one who names and controls creation. In verse 5, “God called the light Day, and the darkness He called Night,” establishing His dominion over time. By naming the firmament “Heaven” in verse 8, God further asserts His sovereign reign over the heavens, an idea that contrasts sharply with the polytheistic beliefs prevalent in the cultures surrounding Israel at the time of Moses.
God’s Sovereignty Versus Ancient Polytheism
The act of naming in the ancient world carried profound significance. Naming something symbolized authority and control over it, an essential point made clear by Kenneth Mathews (Genesis 1-11:26, 1996, p. 150), who emphasizes that by naming the heavens, God claims His dominion over all creation. Unlike the polytheistic religions of Moses’ time, where various gods ruled over different elements of the natural world—such as the sun, moon, or stars—Genesis boldly presents a monotheistic worldview. In contrast to these mythologies, which divided control of the heavens among a pantheon of gods, the biblical account in Genesis shows that there is only one sovereign God who alone creates, controls, and sustains the universe.
Critics often suggest that the Genesis account borrows from contemporary religious beliefs or creation myths, but this assumption fails to recognize the fundamental differences between these narratives. Moses, under divine inspiration, was not copying from other sources; rather, he was offering a direct challenge to the false gods of his day. Genesis teaches that God is not limited to any particular sphere of the cosmos but is Lord over all. The idea of God’s singular rule over the heavens and the earth is a stark departure from the many gods of Canaanite and Mesopotamian cultures, where creation was seen as chaotic and governed by rival deities.
The Threefold Meaning of Heaven in Scripture
The Bible presents the heavens in a threefold way, depending on the context. First, “heaven” can refer to the earth’s atmosphere, the space where birds fly and clouds move. This is likely the intended meaning in Genesis 1:6-8, where God separates the waters below from the waters above and creates the sky, called the “firmament.” This term, “heaven,” is later used in verse 20 to describe the space where the birds will fly, confirming that this refers to the sky, or earth’s atmosphere.
Second, “heaven” can refer to the broader cosmos, including space and the stars. This usage appears earlier in the chapter, likely in Genesis 1:1 and in verses 14-15, when God creates the heavenly bodies—the sun, moon, and stars. In this sense, heaven encompasses everything beyond the earth’s immediate atmosphere, the expanse of the universe that God created and rules over.
Finally, the Bible also speaks of “heaven” as the dwelling place of God, a spiritual realm beyond the physical world. Psalm 11:4 declares, “The LORD is in His holy temple; the LORD’s throne is in heaven,” emphasizing that heaven is where God’s throne is established and where He rules in majesty. This understanding of heaven, while not explicitly mentioned in Genesis 1, forms an essential part of the Bible’s overall teaching about the nature of God’s kingdom and His sovereignty over all creation—physical and spiritual.
