Revelation 21:23 reveals two distinct, yet unified, sources of light for the New Jerusalem. Who are they, and what do they represent?
The verse identifies the light of the New Jerusalem as originating from two powerful, intertwined sources: the glory of God and the Lamb (Jesus Christ).
God's Glory: The Radiant Presence
The "glory of God" refers to His manifest presence, His radiant holiness, and His awesome splendor. It's the very essence of His being that fills the eternal city, providing its light. This is reminiscent of the Shekinah glory that filled the Old Testament tabernacle and temple, but now it's permanent and all-encompassing.
The Lamb: The Focused Light
The "Lamb is the light thereof" points directly to Jesus Christ. He is not just light, but light, described as a 'lamp.' This imagery emphasizes His role as the one who reveals God, illuminates truth, and is the focal point of worship and understanding in heaven. Even in the perfected, glorious presence of God, the identity and work of Jesus as the sacrificial Lamb remain central and are the means by which we fully comprehend and experience God's glory.
