The city had no need of the sun or of the moon to shine in it, for the glory of God illuminated it. The Lamb is its light. Rev. 22:23
This too is another wonder of God. It's really hard to comprehend how this is going to be, but we just have to believe that this is so. It just goes to show that God is so magnificant that we can't even understand. This brings the song "I Can Only Imagine" to mind. As the time changes and it gets dars so early its amazing to think that there will be a time when there will be no more darkness. How awesome! God will be all the light we ever need!
