We will no longer need the sun or the moon, because the Glory of the Lord will be our Everlasting Light. Days of sorrow will be ended. Oh to be in the light of God's eternal glory. I cannot wait to see this day! Read it for yourself from Isaiah 60...
18 No longer will violence be heard in your land,
nor ruin or destruction within your borders,
but you will call your walls Salvation
and your gates Praise.
19 The sun will no more be your light by day,
nor will the brightness of the moon shine on you,
for the LORD will be your everlasting light,
and your God will be your glory.
20 Your sun will never set again,
and your moon will wane no more;
the LORD will be your everlasting light,
and your days of sorrow will end.
