"Order and Rule"
THE FOURTH DAY:
And God said, "Let there be lights in the expanse of the sky to separate the day from the night, and let them serve as signs... and let them be lights in the expanse of the sky to give light on the earth." And it was so. And God saw it was very beautiful. Gen. 1:14-18
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 nations will walk by its light,
"I [Jesus] am the Root and the Offspring of David, and the bright Morning Star." Rev. 21:23-24, 22:16
