In the daytime (for there will be no night there) its gates will never be closed;” (Revelation 21:25, NASB95)

John describes New Jerusalem here and makes an aside comment that “there will be no night there.”  There is no sun either, but in New Jerusalem the sun will not be necessary because:

And the city has no need of the sun or of the moon to shine on it, for the glory of God has illumined it, and its lamp is the Lamb.” (Revelation 21:23, NASB95)

Darkness in the Scriptures, and especially in the writing of John, is associated with bad things, with evil, with the domain of Satan.  Some examples:

  • For those who sleep do their sleeping at night, and those who get drunk get drunk at night. But since we are of the day, let us be sober, having put on the breastplate of faith and love, and as a helmet, the hope of salvation.” (1 Thessalonians 5:7–8, NASB95)
  • The people who were sitting in darkness saw a great Light, And those who were sitting in the land and shadow of death, Upon them a Light dawned.”” (Matthew 4:16, NASB95)
  • The Light shines in the darkness, and the darkness did not comprehend it.” (John 1:5, NASB95)
  • Then Jesus again spoke to them, saying, “I am the Light of the world; he who follows Me will not walk in the darkness, but will have the Light of life.”” (John 8:12, NASB95)
  • “While I was with you daily in the temple, you did not lay hands on Me; but this hour and the power of darkness are yours.”” (Luke 22:53, NASB95)

We could go on, but you get the point.  Light = good, positive, Christ; Darkness = all that is opposite of light. Those who came to arrest Christ had “the power of darkness.”

New Jerusalem when history truly is ended and God has summed up all things in Christ will have no darkness because there is no place for darkness around God. God is light and in him is no darkness at all, writes John elsewhere (1 John 1.5). New Jerusalem is the place where God dwells, what place then for darkness?
