The answer is: Stars

Gen 1:14-19

In the grand narrative of creation found in Genesis, day four highlights God's mighty works when He appointed the sun, moon, and stars. The mention of “stars” might seem overshadowed by the light of the sun and moon, but let's pause and consider their role. Stars not only twinkle in the night sky, creating awe and wonder, but they have also navigated sailors, ushered the arrival of wise men to Bethlehem, and have become symbolic of hope and guidance in countless cultures.

Genesis 1:14-19 tells us that God filled the sky with these celestial bodies more than just providing light; they also delineate seasons and times. Isn’t it fascinating that ancient civilizations throughout history relied on these heavenly bodies for agricultural rhythms and important calendar events? This broad, cosmic view of creation doesn't merely reflect the magnificence of God; it also connects the earthly and divine through the dance of night and day, the transition of seasons, and the rhythms of life itself.

Additionally, the crowning thought from day four is ties into later theological reflections, including the idea that Jesus, referred to as the "Bright Morning Star" in Revelation 22:16, embodies the ultimate fulfillment of light in a far deeper sense. This balance—between an intricate cosmos and individual purpose—is worth appreciating as we contemplate our role within this beautifully crafted universe.
