22:4 They shall see his face. See Mt 5:8. They shall enjoy the visible presence of the Lamb.
And his name [shall be] in their foreheads. Written by God's finger. It shall always be seen and known that they are his.
22:4 And shall see his face - Which was not granted to Moses. They shall have the nearest access to, and thence the highest resemblance of, him. This is the highest expression in the language of scripture to denote the most perfect happiness of the heavenly state, 1John 3:2. And his name shall be on their foreheads - Each of them shall be openly acknowledged as God's own property, and his glorious nature most visibly shine forth in them. And they shall reign - But who are the subjects of these kings? The other inhabitants of the new earth. For there must needs be an everlasting difference between those who when on earth excelled in virtue, and those comparatively slothful and unprofitable servants, who were just saved as by fire. The kingdom of God is taken by force; but the prize is worth all the labour. Whatever of high, lovely, or excellent is in all the monarchies of the earth is all together not a grain of dust, compared to the glory of the children of God. God is not ashamed to be called their God, for whom he hath prepared this city. But who shall come up into his holy place? They who keep his commandments, verse 14. Rev 22:14
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!
