The heavenly state which was before described as a city, and called the new Jerusalem, is here described as a paradise, alluding to the earthly paradise which was lost by the sin of the first Adam; here is another paradise restored by the second Adam. A paradise in a city, or a whole city in a paradise! In the first paradise there were only two persons to behold the beauty and taste the pleasures of it; but in this second paradise whole cities and nations shall find abundant delight and satisfaction. And here observe,

I.The river of paradise. The earthly paradise was well watered: no place can be pleasant or fruitful that is not so. This river is described, 1. By its fountain-head - the throne of God and the Lamb. All our springs of grace, comfort, and glory, are in God; and all our streams from him are through the mediation of the Lamb. 2. By its quality - pure and clear as crystal. All the streams of earthly comfort are muddy; but these are clear, salutary, and refreshing, giving life, and preserving life, to those who drink of them.

II.The tree of life, in this paradise. Such a tree there was in the earthly paradise, Gen 2:9. This far excels it. And now, as to this tree, observe, 1. The situation of it - in the midst of the street, and on either side the river; or, as might have been better rendered, in the midst between the terrace-walk and the river. This tree of life is fed by the pure waters of the river that comes from the throne of God. The presence and perfections of God furnish out all the glory and blessedness of heaven. 2. The fruitfulness of this tree. (1.) It brings forth many sorts of fruit - twelve sorts, suited to the refined taste of all the saints. (2.) It brings forth fruit at all times - yields its fruit every month. This tree is never empty, never barren; there is always fruit upon it. In heaven there is not only a variety of pure and satisfying pleasures, but a continuance of them, and always fresh. (3.) The fruit is not only pleasant, but wholesome. The presence of God in heaven is the health and happiness of the saints; there they find in him a remedy for all their former maladies, and are preserved by him in the most healthful and vigorous state.

III.The perfect freedom of this paradise from every thing that is evil (Rev 22:3): There shall be no more curse; no accursed one - katanathema, no serpent there, as there was in the earthly paradise. Here is the great excellency of this paradise. The devil has nothing to do there; he cannot draw the saints from serving God to be subject to himself, as he did our first parents, nor can he so much as disturb them in the service of God.

IV.The supreme felicity of this paradisiacal state. 1. There the saints shall see the face of God; there they shall enjoy the beatific vision. 2. God will own them, as having his seal and name on their foreheads. 3. They shall reign with him for ever; their service shall be not only freedom but honour and dominion. 4. All this shall be with perfect knowledge and joy. They shall be full of wisdom and comfort, continually walking in the light of the Lord; and this not for a time, but for ever and ever.

See his face - Enjoy what is called the beatific vision; and they shall exhibit the fullest evidence that they belong entirely to him, for his name shall be written on their foreheads.

And they shall see his face,.... The face of God, so as he is not to be seen now; they shall see him as he is; not only the angels, who always behold the face of God, but all the saints, risen and changed, being pure in heart, and perfectly holy; they shall see him face to face, they shall have intimate and familiar communion with him; they shall enjoy his favour, and have the freest and largest discoveries of his love; and they shall see the face of the Lamb; they shall behold Christ and his glory both with the eyes of their understanding, and with the eyes of their bodies; and this is a very desirable sight, and will be very glorious and delightful; it will be fully satisfying, and will make the saints like unto him; it will be free from all darkness and any interruption, and will always continue.

And his name shall be in their foreheads; they shall be known to be his servants, as if his name was written and bore on their foreheads; it will be a clear case that they are the children and people of God; now they are, but it is not known, at least not so known as it will be in this state; and they will also in the fullest and freest manner own God to be their God, and the Lamb to be their Redeemer; they will be under no fear of man, nor be under any temptation to be ashamed of Christ, or of his service; see Rev 14:1. Some think there is an allusion to the inscription on the mitre of the high priest's forehead, "holiness to the Lord", the saints being now openly, visibly, and perfectly holy.

see his face--revealed in divine glory, in Christ Jesus. They shall see and know Him with intuitive knowledge of Him, even as they are known by Him (Co1 13:9-12), and face to face. Compare Ti1 6:16, with Joh 14:9. God the Father can only be seen in Christ.

in--Greek, "on their foreheads." Not only shall they personally and in secret (Rev 3:17) know their sonship, but they shall be known as sons of God to all the citizens of the new Jerusalem, so that the free flow of mutual love among the members of Christ's family will not be checked by suspicion as here.
