And the city has no need of the sun nor of the moon to give light to it, for the splendor and radiance (glory) of God illuminate it, and the Lamb is its lamp - Rev 21:23
Even as the greatness of God cannot be searched out and understood, so also is His dwelling. Where a king dwells speaks volumes about his personality and status. Heaven, being the Lord's dwelling place, radiates the beauty, glory and wonders of God. The glory of heaven is revealed in its dimensions, architecture, designs and dwellers.
The foundation and structures of heaven were built with gold and precious stones. The lighting of heaven is not supported with complex power transmission because God Himself is the Light. Because God doesn't sleep nor slumber, so heaven doesn't go on power failure.
On earth, we determine the period of a day using morning, day and night. But in heaven, there is no seasonal division as morning, noon and night. Every moment in heaven is morning since there is no gathering as vigils. That could explain why Lucifer was called the son of the morning, with the mission to give God continuous praise.
Knowing that heaven is exceedingly glorious, then it takes a glorious church to dwell with God in eternity. Are you a member of the glorious church which Christ longs to present to Himself and for whom He has gone to prepare a glorious place? I pray that in the end, your name shall be found in the glorious Book of Life in Jesus name.
