What was the light source before Day 4?
If light existed on Day 1 (Genesis 1:3–5) but the sun wasn’t formed until Day 4, what was the initial source of light?

Genesis 1 and the Presence of Light Before the Sun

Genesis 1:3–5 reads: “And God said, ‘Let there be light,’ and there was light. And God saw that the light was good, and He separated the light from the darkness. God called the light ‘day,’ and the darkness He called ‘night.’ And there was evening, and there was morning—the first day.” These verses highlight that light appeared on the very first day of creation, yet the text later specifies the creation of the sun, moon, and stars on the fourth day (Genesis 1:14–19). This has led to the question: “If light existed on Day 1, what was its source prior to the formation of the sun on Day 4?”

Below is an exhaustive look at how to understand and reconcile this question.


1. Clarification of the Timing of Creation

Scripture indicates that God created everything in six distinct days (Genesis 1:1–31). Archbishop James Ussher and others holding to a young-earth timeline have organized biblical genealogies to estimate that these events occurred roughly six thousand years ago. According to this reading, the establishment of “light” on Day 1 and the subsequent formation of the sun on Day 4 are neither contradictory nor incongruous when considering that God can create light independently of the celestial bodies.

Ancient biblical manuscript evidence, such as the Masoretic Text and portions of the text found among the Dead Sea Scrolls, corroborates the wording we have in modern Bibles. These preserved texts strengthen confidence that Genesis 1 is accurately transmitted to us.


2. Scriptural Observations and Interpretations

A. Direct Command of Light

The passage states that God spoke light into existence (Genesis 1:3). The text does not indicate that God needed a physical luminary, but rather that God Himself generated or called forth luminosity. Since the Bible consistently teaches that God has the power to create ex nihilo (“out of nothing”), the creation of light by His sheer command falls within the realm of His sovereign ability.

B. God’s Own Glory as a Light Source

Scripture elsewhere points to God’s radiance. Revelation 21:23 says, “And the city has no need of sun or moon to shine on it, because the glory of God illuminates the city, and the Lamb is its lamp.” God’s glory can serve as a source of light, distinct and independent from physical suns or stars. The same principle could have been true in Genesis 1, where God’s own presence illuminated creation prior to the sun’s creation on Day 4.


3. Parallel Biblical References

A. Job’s Depictions of Creation

Job 38:4, 19 records God speaking to Job about creation: “Where were you when I laid the foundations of the earth? Tell Me, if you have understanding… Where is the way to the home of light?” Such lines underscore that light’s origin resides with God, and He alone fully understands its source and pathways. This further suggests that light is not necessarily confined to a single physical object like the sun.

B. John’s Creation Allusion

In John 1:1–5, it is stated that “In the beginning was the Word… In Him was life, and that life was the light of men.” This description reveals a deeper layer: the light of creation may also be a reflection of God’s nature and His living Word. It supports the view that physical light, like truth and life, can be rooted directly in God’s being.


4. Theological Perspectives on the Source of Day One Light

A. God’s Creative Power

Some hold that the light was a temporary, supernatural luminescence manifested by God until the sun was created on Day 4. This underscored His complete sovereignty, showcasing that God’s creation is not dependent on the natural mechanisms we commonly observe today.

B. The “Shekinah” Glory

While the Hebrew Bible never explicitly uses the word “Shekinah,” the concept of brilliant Divine Presence—often referred to by this term—appears in various passages where God’s presence manifests in a visually luminous form (e.g., Exodus 40:34–35). This cloud of glorious light is a possible explanation for the Day 1 light. If God’s glory illumines heaven (Revelation 21:23), it could easily illumine earth prior to day four.


5. Historical and Apologetic Insights

A. Consistency with Ancient Manuscripts and Archaeological Discoveries

The consistency among manuscripts such as the Septuagint, Samaritan Pentateuch, Masoretic Text, and the Dead Sea Scrolls affirms that Genesis 1 as we read it today is not a later editing error. Archaeological discoveries, such as those of ancient near-eastern texts, also highlight that the biblical creation account stands apart in its emphasis on a transcendent God who creates from nothing, rather than being shaped by cosmic conflict or relying on pre-existing matter.

B. Young-Earth Intelligent Design Perspective

Advocates of a young-earth perspective point to scientific findings that emphasize the complexities of life from the very beginning, indicating design. For instance, irreducible complexities in cellular biology, the lack of transitional fossils in the geological record, and the appearance of “sudden” biological forms support the idea that creation came about through divine intentionality rather than gradualistic, unaided processes. None of these fields demand that light must originate solely from the sun; instead, they highlight the personal agency of a Creator who can introduce light in any manner He chooses.


6. Role of Faith and Logical Consistency

Some hold that while the phenomenon on Day 1 may seem mysterious, it parallels other biblical miracles that defy conventional explanation, such as the Resurrection of Christ. The biblical text maintains an internal consistency: if God is eternal, beyond physical constraints, He can produce light without the sun and can also raise Jesus from the dead. Accepting this premise from the opening chapters of Scripture equips believers to recognize other miracles—both biblical and modern—as congruent with God’s nature and His involvement in the world.


7. Conclusion

The statement “Let there be light” (Genesis 1:3) is not contingent upon the sun’s existence. Rather, it flows from the power and prerogative of God’s creative word. The opening of Genesis demonstrates that light can derive from the divine presence itself, and the later creation of the sun as a permanent luminary fits seamlessly with that progression.

Biblically, light is first a demonstration of God’s glory and creative action, underscoring that God transcends His creation and is not restricted by it. Historically, manuscript evidence and theological interpretations have upheld the consistency of this reading. By understanding that God’s own radiance, or an immediately created light source, provided illumination on the first day, believers can affirm both the authority of Scripture and the coherence of the biblical account of creation.
