Isaiah 30:26
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.
Will the light of the sun and moon be increased or decreased in the future kingdom?
PROBLEM: Isaiah has two apparently contradictory predictions. One is that the light to the heavenly bodies will be increased sevenfold (Isaiah 30:26). The other is that it will be “ashamed” in the light of the Lord Himself (Isaiah 24:23).
SOLUTION: Some scholars believe these are mutually compatible poetic predictions that even though the light of the sun and moon is increased manifold (perhaps, figuratively), nevertheless, the light of the Lord will outshine them.
Others take these as literal predictions about two different future times. They hold that the natural light of the heavenly bodies will be increased during the reign of Christ for “a thousand years” (Revelation 20:4-6). But after that, when the “new heaven and a new earth” (Revelation 21:1) are created, there will be “no need of the sun or of the moon to shine in it, for the glory of God illuminated it” (Revelation 21:23).
