Here we have a description of the honour and happiness of those who have faithfully served the Lord Jesus Christ, and suffered for him. Observe,

I.A question asked by one of the elders, not for his own information, but for John's instruction: ministers may learn from the people, especially from aged and experienced Christians; the lowest saint in heaven knows more than the greatest apostle in the world. Now the question has two parts: - 1. What are these that are arrayed in white robes? 2. Whence came they? It seems to be spoken by way of admiration, as Sol 3:6, Who is this that cometh out of the wilderness! Faithful Christians deserve our notice and respect; we should mark the upright.

II.The answer returned by the apostle, in which he tacitly acknowledges his own ignorance, and sues to this elder for information: Thou knowest. Those who would gain knowledge must not be ashamed to own their ignorance, nor to desire instruction from any that are able to give it.

III.The account given to the apostle concerning that noble army of martyrs who stood before the throne of God in white robes, with palms of victory in their hands: and notice is taken here of, 1. The low and desolate state they had formerly been in; they had been in great tribulation, persecuted by men, tempted by Satan, sometimes troubled in their own spirits; they had suffered the spoiling of their goods, the imprisonment of their persons, yea, the loss of life itself. The way to heaven lies through many tribulations; but tribulation, how great soever, shall not separate us from the love of God. Tribulation, when gone through well, will make heaven more welcome and more glorious. 2. The means by which they had been prepared for the great honour and happiness they now enjoyed: they had washed their robes, and made them white in the blood of the Lamb, Rev 7:14. It is not the blood of the martyrs themselves, but the blood of the Lamb, that can wash away sin, and make the soul pure and clean in the sight of God. Other blood stains; this is the only blood that makes the robes of the saints white and clean. 3. The blessedness to which they are now advanced, being thus prepared for it. (1.) They are happy in their station, for they are before the throne of God night and day; and he dwells among them; they are in that presence where there is fulness of joy. (2.) They are happy in their employment, for they serve God continually, and that without weakness, drowsiness, or weariness. Heaven is a state of service, though not of suffering; it is a state of rest, but not of sloth; it is a praising delightful rest. (3.) They are happy in their freedom from all the inconveniences of this present life. [1.] From all want and sense of want: They hunger and thirst no more; all their wants are supplied, and all the uneasiness caused thereby is removed. [2.] From all sickness and pain: they shall never be scorched by the heat of the sun any more. (4.) They are happy in the love and guidance of the Lord Jesus: He shall feed them, he shall lead them to living fountains of waters, he shall put them into the possession of every thing that is pleasant and refreshing to their souls, and therefore they shall hunger and thirst no more. (5.) They are happy in being delivered from all sorrow or occasion of it: God shall wipe away all tears from their eyes. They have formerly had their sorrows, and shed many tears, both upon the account of sin and affliction; but God himself, with his own gentle and gracious hand, will wipe those tears away, and they shall return no more for ever; and they would not have been without those tears, when God comes to wipe them away. In this he deals with them as a tender father who finds his beloved child in tears, he comforts him, he wipes his eyes, and turns his sorrow into rejoicing. This should moderate the Christian's sorrow in his present state, and support him under all the troubles of it; for those that sow in tears shall reap in joy; and those that now go forth weeping, bearing precious seed, shall doubtless come again rejoicing, bringing their sheaves with them.

Therefore - Because they are washed in the blood of the Lamb, are they before the throne - admitted to the immediate presence, of God.

And serve him day and night - Without ceasing; being filled with the spirit of prayer, faith, love, and obedience.

Shall dwell among them - He lives in his own Church, and in the heart of every true believer.

Therefore are they before the throne of God,.... See Gill on Rev 7:9; not because of their great tribulations, but because they were brought through them, and out of them, by the grace and power of God; nor because of their robes, or conversation garments, but because those were washed and made white in the blood of the Lamb; or because of the blood of the Lamb, and their justification, pardon, and cleansing by it:

and serve him day and night in his temple; not in any material temple, but in the new Jerusalem, the general assembly and church of the firstborn, the temple of the living God; for in this state there will be no material temple, or place of worship, but God and the Lamb will be the temple thereof, Rev 21:22; nor will there be any night there, Rev 22:5; wherefore this phrase, day and night, only denotes the constancy and uninterruption of their service, there being nothing to obstruct them in it, or break them off from it, as now; in allusion to the priests and Levites, who were, one or other of them, night or day in the service of the temple: and the service of these persons in the new Jerusalem state will not lie in attending on the word and ordinances, or in the ministration of them, as in the present state; but in praising God, singing Hallelujahs to him, adoring the perfections of his nature, and admiring his wonderful works of providence and grace, and ascribing the glory of salvation to him, and to the Lamb; and this their service will be the glorious liberty of the children of God. Hence the Ethiopic version renders it, "and they praise him day and night"; this will be the employment of the saints in the millennium state, and to all eternity:

and he that sitteth on the throne shall dwell among them; or "tabernacle over them"; for the tabernacle of God shall be now among men, and he will dwell among the saints; they shall enjoy his presence, and have the most intimate communion with him; it will appear most manifest that he is their covenant God, and they are his covenant people; and he will be a tabernacle, not only of inhabitation, but of protection for them; and the name of this city, this new Jerusalem, will be "Jehovah Shammah", the Lord is there.

Therefore--because they are so washed white; for without it they could never have entered God's holy heaven; Rev 22:14, "Blessed are those who wash their robes (the oldest manuscripts reading), that they may have right to the tree of life, and may enter in through the gates into the city"; Rev 21:27; Eph 5:26-27.

before--Greek, "in the presence of." Mat 5:8; Co1 13:12, "face to face."

throne . . . temple--These are connected because we can approach the heavenly King only through priestly mediation; therefore, Christ is at once King and Priest on His throne.

day and night--that is, perpetually; as those approved of as priests by the Sanhedrim were clothed in white, and kept by turns a perpetual watch in the temple at Jerusalem; compare as to the singers, Ch1 9:33, "day and night"; Psa 134:1. Strictly "there is no night" in the heavenly sanctuary (Rev 22:5).

in his temple--in what is the heavenly analogue to His temple on earth, for strictly there is "no temple therein" (Rev 21:22), "God and the Lamb are the temple" filling the whole, so that there is no distinction of sacred and secular places; the city is the temple, and the temple the city. Compare Rev 4:8, "the four living creatures rest not day and night, saying, Holy," &c.

shall dwell among them--rather (Greek, "scenosei ep' autous"), "shall be the tabernacle over them" (compare Rev 21:3; Lev 26:11, especially Isa 4:5-6; Isa 8:14; Isa 25:4; Eze 37:27). His dwelling among them is to be understood as a secondary truth, besides what is expressed, namely, His being their covert. When once He tabernacled among us as the Word made flesh, He was in great lowliness; then He shall be in great glory.
