Revelation 21:23 The Lamb is the light thereof.
Quietly contemplate the Lamb as the light of heaven. Light in Scripture is the emblem of joy. The joy of the saints in heaven is comprised in this: Jesus chose us, loved us, bought us, cleansed us, robed us, kept us, glorified us: we are here entirely through the Lord Jesus. Each one of these thoughts shall be to them like a cluster of the grapes of Eshcol. Light is also the cause of beauty. Nought of beauty is left when light is gone. Without light no radiance flashes from the sapphire, no peaceful ray proceedeth from the pearl; and thus all the beauty of the saints above comes from Jesus. As planets, they reflect the light of the Sun of Righteousness; they live as beams proceeding from the central orb. If he withdrew, they must die; if his glory were veiled, their glory must expire. Light is also the emblem of knowledge. In heaven our knowledge will be perfect, but the Lord Jesus himself will be the fountain of it. Dark providences, never understood before, will then be clearly seen, and all that puzzles us now will become plain to us in the light of the Lamb. Oh! what unfoldings there will be and what glorifying of the God of love! Light also means manifestation. Light manifests. In this world it doth not yet appear what we shall be. God's people are a hidden people, but when Christ receives his people into heaven, he will touch them with the wand of his own love, and change them into the image of his manifested glory. They were poor and wretched, but what a transformation! They were stained with sin, but one touch of his finger, and they are bright as the sun, and clear as crystal. Oh! what a manifestation! All this proceeds from the exalted Lamb. Whatever there may be of effulgent splendour, Jesus shall be the centre and soul of it all. Oh! To be present and to see him in his own light, the King of kings, and Lord of lords!
