When the Lord restores the earth to sinless perfection the light will be 7 times brighter. Here are some examples to imagine how it would be compared to if the light was 7 times brighter here on this fallen earth -
If the sun became seven times brighter on the current fallen Earth, the effects would be extreme, even if the heat didn’t increase proportionally. This idea is found in Isaiah 30:26:
"Moreover the light of the moon shall be as the light of the sun, and the light of the sun shall be sevenfold, as the light of seven days, in the day that the Lord bindeth up the breach of his people, and healeth the stroke of their wound." (KJV)
This verse suggests a future time when the light will be far more intense, Here’s what that could mean for the current Earth:
1. Vision and Eye Damage
Even indirect sunlight would be painfully bright, making it nearly impossible to go outside without extreme eye protection.
Constant exposure could cause photokeratitis (sunburned eyes) and permanent retinal damage.
People would need heavily tinted glasses, and even indoor lighting would have to change to avoid excessive brightness.
2. Environmental Changes
A sevenfold increase in visible light would likely affect plant growth—some plants might thrive with more light, while others could be overstimulated and die.
Glaciers and ice caps could melt faster due to increased light absorption, even if heat didn’t rise dramatically.
Colors would appear more intense, possibly altering how we perceive the world visually.
3. Skin and Health Effects
UV exposure would likely increase, leading to more skin cancers, burns, and premature aging.
Even with sunscreen, people might need to cover their skin completely when outdoors.
4. Psychological and Lifestyle Changes
People might avoid daylight hours, becoming more nocturnal.
Cities would need darker windows, underground spaces, or adaptive architecture to cope with the brightness.
Migraines and sleep cycle disruptions could become common since excessive light affects melatonin production.
However, this prophecy refers to heaven or the New Jerusalem, the light would be God’s glory, not harmful sunlight. Revelation 21:23 says:
"And the city had no need of the sun, neither of the moon, to shine in it: for the glory of God did lighten it, and the Lamb is the light thereof." (KJV)
This suggests that, unlike earthly sunlight, God’s light will be pure, life-giving, and not harmful. Instead of burning or blinding, it will illuminate everything with divine clarity.
