For countless generations people have looked to the sun and moon to light the day and the night. Whether illuminating our path or providing the life-giving radiance for fruitful crops and the nutrients our bodies need, the sun and moon are part of God’s marvelous provision of light. The book of Genesis tells us that God gave “the greater light to rule the day, and the lesser light to rule the night” (Gen. 1:16).

But someday God will provide a different kind of illumination. Of the eternal heavenly city, John writes: “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. 21:23). Interestingly, the word translated “light” here is more accurately rendered lamp. Christ in His glorified state will be the spiritual lamp that lights up that joyous new world.

The Lord Jesus Christ is “the Lamb of God who takes away the sin of the world” (John 1:29). He is also the source of spiritual illumination that makes those who follow Him “the light of the world” (Matt. 5:14). But in eternity He will be the Lamp that lights our way (Rev. 21:23). What a thrill it will be one day to live in the light of the Lamb!
