Contradiction with Revelation 22:5
This verse speaks of a place where there is no need for the sun or moon, as opposed to Isaiah 60:20 which suggests the continuation of eternal light from the sun and moon.
Revelation 22:5: And there shall be no night there; and they need no candle, neither light of the sun; for the Lord God giveth them light: and they shall reign for ever and ever.
Contradiction with Ecclesiastes 1:5
This verse describes the cycle of the sun rising and setting repeatedly, which is contrary to the permanence of light described in Isaiah 60:20.
Ecclesiastes 1:5: The sun also ariseth, and the sun goeth down, and hasteth to his place where he arose. [hasteth: Heb. panteth]
Contradiction with Matthew 24:29
Indicates that the sun and moon will not give their light during the end times, contrasting Isaiah 60:20's promise of everlasting light.
Matthew 24:29: Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken:
Paradox #1
The contradiction or inconsistency with Isaiah 60:20 might be around the idea of eternal light and joy. Historically, Israel faced many challenges and periods of suffering, which might seem at odds with the promise of perpetual light and joy. This can be seen as a prophetic vision that contrasts with the actual historical experiences of the people.
Paradox #2
One possible contradiction with this verse could be the implication that the sun and moon will no longer be necessary for providing light. Scientifically, the sun is essential for daylight and life on Earth due to its energy and light, and the moon has observable effects on tides and nocturnal light. So, suggesting these celestial bodies are no longer needed contradicts our understanding of their critical roles in Earth's natural systems.
