And I heard a voice from heaven saying unto me, Write, Blessed are the dead which die {b} in the Lord from henceforth: Yea, saith the Spirit, that they may rest from their labours; and their {c} works do follow them.

(b) That is, for the Lord.

(c) By works, is meant the reward which follows good works.

People's New Testament

14:13 I heard a voice from heaven saying unto me, Write. We are not told whose voice, but it is a voice of authority. The words to be written are next stated. Blessed are the dead which die in the Lord. Not all the dead, but those dead who die in the Lord. Only those die in the Lord who are in the Lord when they die. The Christian life, begun by faith and baptism into Christ (Ro 6:3), is a life in Christ. To be assured of this blessed death one must live a Christian life. From henceforth. Probably from the time of this utterance to John, though some have supposed that the time meant is that of the Lord's coming, which is declared in Re 14:14. Yea, saith the Spirit. The Spirit confirms the blessing pronounced and states the reason. That they may rest from their labours. Yet though they rest their labors are not lost; they follow them to eternity to speak for them.

Wesley's Notes

14:13 And I heard a voice - This is most seasonably heard when the beast is in his highest power and fury. Out of heaven - Probably from a departed saint. Write - He was at first commanded to write the whole book. Whenever this is repeated it denotes something peculiarly observable. Happy are the dead - From henceforth particularly:
1. Because they escape the approaching calamities:
2. Because they already enjoy so near an approach to glory. Who die in the Lord - In the faith of the Lord Jesus. For they rest - No pain, no purgatory follows; but pure, unmixed happiness. From their labours - And the more laborious their life was, the sweeter is their rest. How different this state from that of those, verse 11, Rev 14:11 who have no rest day or night! Reader, which wilt thou choose? Their works - Each one's peculiar works. Follow - or accompany them; that is, the fruit of their works. Their works do not go before to procure them admittance into the mansions of joy; but they follow them when admitted.

King James Translators' Notes

from henceforth...: or, from henceforth saith the Spirit, Yea

Jamieson-Fausset-Brown Bible Commentary

13. Encouragement to cheer those persecuted under the beast.

Write-to put it on record for ever.

Blessed-in resting from their toils, and, in the case of the saints just before alluded to as persecuted by the beast, in resting from persecutions. Their full blessedness is now "from henceforth," that is, FROM THIS TIME, when the judgment on the beast and the harvest gatherings of the elect are imminent. The time so earnestly longed for by former martyrs is now all but come; the full number of their fellow servants is on the verge of completion; they have no longer to "rest (the same Greek as here, anapausis) yet for a little season," their eternal rest, or cessation from toils (2Th 1:7; Greek, "anesis," relaxation after hardships. Heb 4:9, 10, sabbatism of rest; and Greek, "catapausis," akin to the Greek here) is close at hand now. They are blessed in being about to sit down to the marriage supper of the Lamb (Re 19:9), and in having part in the first resurrection (Re 20:6), and in having right to the tree of life (Re 22:14). In Re 14:14-16 follows the explanation of why they are pronounced "blessed" now in particular, namely, the Son of man on the cloud is just coming to gather them in as the harvest ripe for garner.

Yea, saith the Spirit-The words of God the Father (the "voice from heaven") are echoed back and confirmed by the Spirit (speaking in the Word, Re 2:7; 22:17; and in the saints, 2Co 5:5; 1Pe 4:14). All "God's promises in Christ are yea" (2Co 1:20).

unto me-omitted in A, B, C, Vulgate, Syriac, and Coptic.

that they may-The Greek includes also the idea, They are blessed, in that they SHALL rest from their toils (so the Greek).

and-So B and Andreas read. But A, C, Vulgate, and Syriac read "for." They rest from their toils because their time for toil is past; they enter on the blessed rest because of their faith evinced by their works which, therefore, "follow WITH (so the Greek) them." Their works are specified because respect is had to the coming judgment, wherein every man shall be "judged according to his works." His works do not go before the believer, nor even go by his side, but follow him at the same time that they go with him as a proof that he is Christ's.

Matthew Henry's Concise Commentary

14:6-13 The progress of the Reformation appears to be here set forth. The four proclamations are plain in their meaning; that all Christians may be encouraged, in the time of trial, to be faithful to their Lord. The gospel is the great means whereby men are brought to fear God, and to give glory to him. The preaching of the everlasting gospel shakes the foundations of antichrist in the world, and hastens its downfal. If any persist in being subject to the beast, and in promoting his cause, they must expect to be for ever miserable in soul and body. The believer is to venture or suffer any thing in obeying the commandments of God, and professing the faith of Jesus. May God bestow this patience upon us. Observe the description of those that are and shall be blessed: such as die in the Lord; die in the cause of Christ, in a state of union with Christ; such as are found in Christ when death comes. They rest from all sin, temptation, sorrow, and persecution; for there the wicked cease from troubling, there the weary are at rest. Their works follow them: do not go before as their title, or purchase, but follow them as proofs of their having lived and died in the Lord: the remembrance of them will be pleasant, and the reward far above all their services and sufferings. This is made sure by the testimony of the Spirit, witnessing with their spirits, and the written word.
