Revelation 22:5 says about New Jerusalem, “Night will be no more; and they have no need of the light of a lamp and of the light of the sun, for the Lord God will shine upon them.” The sun is one of the natural lights created by God and a lamp is one of the artificial lights made by men. Neither of them are needed in New Jerusalem.
The light of New Jerusalem is God Himself in Christ Jesus. This is Revelation 21:23, “The city has no need of the sun or of the moon that they should shine in it, for the glory of God illumined it, and its lamp is the Lamb.”
God is light (1 John 1:5) and Jesus Christ is the light of life (John 1:4). They are not two separate lights; God is in Christ and shines through Him today. In New Jerusalem the glorious God shines from within the Lamb-Lamp.
In the ancient times the outer court of the tabernacle was lit by the sun during the day and by the moon at night, and the Holy Place was lit by the lampstand. In the Holy of Holies, however, there was no sun, no moon, and no lampstand. The light in the Holy of Holies was God Himself in His eternal glory….Besides the New Jerusalem, the Holy of Holies in both the tabernacle and the temple is the only structure in the entire Scriptures that is equal in three dimensions. Similarly, the Holy of Holies is the only other place where there is need of no light other than God. This shows that in eternity the holy city will be the Holy of Holies. In the New Jerusalem God Himself in Christ will be everything to us. The Triune God will also be our light to enlighten us. Here we have the intrinsic essence of the New Jerusalem.°
Thank you Lord Jesus that You are our light of life today. Enlighten us more today.
