221 Then the angel showed me the river of the water of life, as clear as crystal, flowing from the throne of God and of the Lamb 2 down the middle of the great street of the city. On each side of the river stood the tree of life, bearing twelve crops of fruit, yielding its fruit every month. And the leaves of the tree are for the healing of the nations. 3 No longer will there be any curse. The throne of God and of the Lamb will be in the city, and his servants will serve him. 4 They will see his face, and his name will be on their foreheads. 5 There will be no more night. They will not need the light of a lamp or the light of the sun, for the Lord God will give them light. And they will reign for ever and ever.

Commentary on Revelation 22:1-5

(Read Revelation 22:1-5)

All streams of earthly comfort are muddy; but these are clear, and refreshing. They give life, and preserve life, to those who drink of them, and thus they will flow for evermore. These point to the quickening and sanctifying influences of the Holy Spirit, as given to sinners through Christ. The Holy Spirit, proceeding from the Father and the Son, applies this salvation to our souls by his new-creating love and power. The trees of life are fed by the pure waters of the river that comes from the throne of God. The presence of God in heaven, is the health and happiness of the saints. This tree was an emblem of Christ, and of all the blessings of his salvation; and the leaves for the healing of the nations, mean that his favour and presence supply all good to the inhabitants of that blessed world. The devil has no power there; he cannot draw the saints from serving God, nor can he disturb them in the service of God. God and the Lamb are here spoken of as one. Service there shall be not only freedom, but honour and dominion. There will be no night; no affliction or dejection, no pause in service or enjoyment: no diversions or pleasures or man's inventing will there be wanted. How different all this from gross and merely human views of heavenly happiness, even those which refer to pleasures of the mind!
