Revelation 21:23 (New International Version)
23 The city does not need the sun or the moon to shine on it, for the glory of God gives it light, and the Lamb is its lamp.
The sun and the moon appear in the opening pages of the Bible, on the fourth day of creation. Here, in the closing pages of the Bible, the sun and moon are declared redundant.
Yes, the sun, described in Psalm 19 in glowing terms as a bridegroom and a champion, is now superseded. The brilliant radiation of the sun, which floods the earth with heat and light and so sustains life, is now eclipsed by a greater glory. The sun pales into insignificance in the face of the glory of God and the Lamb.
And just as the sun physically illuminates the whole earth, so the heavenly spiritual radiance bathes the entire planet. “The nations will walk by its light, and the kings of the earth will bring their splendour into it”. Jesus is not just our light or Israel’s light but Jesus is the light of the world; and whoever – whoever – follows him will never walk in darkness, but will have the light of life (John 8:12).
