If we do not infer modern secular cosmology onto the text then yes the moon is a light and not a rock. The sun likewise is a light and not a gaseous star.
“And God said, “Let there be lights in the expanse of the heavens to separate the day from the night. And let them be for signs and for seasons, and for days and years, and let them be lights in the expanse of the heavens to give light upon the earth.” And it was so. And God made the two great lights—the greater light to rule the day and the lesser light to rule the night—and the stars.”
Genesis 1:14-16
God did not say let there be a light and a reflector. In Biblical cosmology the moon is a light and it gives its own light.
It is for this reason that throughout Scripture including the NT that the moon is seen has a light and the possessor of its own light and not a reflector.
“For the stars of the heavens and their constellations will not give their light; the sun will be dark at its rising, and the moon will not shed its light.”
Isaiah 13:10
“Moreover, the light of the moon will be as the light of the sun, and the light of the sun will be sevenfold, as the light of seven days, in the day when the Lord binds up the brokenness of his people, and heals the wounds inflicted by his blow.”
Isaiah 30:26
“When I blot you out, I will cover the heavens and make their stars dark; I will cover the sun with a cloud, and the moon shall not give its light.”
Ezekiel 32:7
We can rest assured that Jesus being the Creator knew exactly what He had created looked like, how it behaved and it’s properties.
“Immediately after the tribulation of those days the sun will be darkened, and the moon will not give its light, and the stars will fall from heaven, and the powers of the heavens will be shaken.”
Matthew 24:29
Even Jesus says the moon has its own light because from the beginning He created the moon to be a light and not a rock and not a reflector.
If the moon were a reflector then when the sunlight is removed the moon should have less light to reflect. If the sun is darkened enough or turned to darkness meaning the light is completely off then the moon should have no light at all. Yet the moon is visible and a different color. The reflection idea from 92 million miles away is hopeless wrong
“The sun shall be turned to darkness, and the moon to blood, before the great and awesome day of the Lord comes.”
Joel 2:31
