Today's reading is very short, just 6 verses. I particularly like the first section of today's reading. In this section, it is stated that the heavenly city needs no light in the usual sense. "The city does not need the sun or the moon." (v. 23).
To me, this description brings two complementary pictures to mind. First, verse 23 goes on to say, "for the glory of God gives it light". Obviously God more than makes up for the absence of the sun and the moon. His glory is brighter than the sun!! Further He will be there with us day and night, forever.
Second, and parallel, and maybe not quite so obvious, verse 23 further states, "and the Lamb is its lamp". Physical light is often a biblical picture for spiritual and moral right. The presence of an everlasting lamp points to the permanent overthrow of sin and evil. In his Gospel, John recorded Jesus' statement, "I am the light of the world" (John 8:12). This section reminds us that the Lamb will utterly defeat any darkness.
To me, today's short reading is very encouraging and reassuring. We can be assured that God will ultimately destroy evil and that He will be eternally present with his people in heaven. I hope you agree this is very good news on this day of Epiphany.
Wishing you the best in your walk with Christ,
