Day of the Lord

Concise Bible Dictionary:

This cannot be separated from Messiah’s day. It is often characterized by judgment: “A day of darkness and of gloominess, a day of clouds and of thick darkness.... the day of the Lord is great and very terrible” (Joel 2:2, 11, 312A day of darkness and of gloominess, a day of clouds and of thick darkness, as the morning spread upon the mountains: a great people and a strong; there hath not been ever the like, neither shall be any more after it, even to the years of many generations. (Joel 2:2)
11And the Lord shall utter his voice before his army: for his camp is very great: for he is strong that executeth his word: for the day of the Lord is great and very terrible; and who can abide it? (Joel 2:11)
31The sun shall be turned into darkness, and the moon into blood, before the great and the terrible day of the Lord come. (Joel 2:31); Mal. 4:11For, behold, the day cometh, that shall burn as an oven; and all the proud, yea, and all that do wickedly, shall be stubble: and the day that cometh shall burn them up, saith the Lord of hosts, that it shall leave them neither root nor branch. (Malachi 4:1)). “The day of the Lord so cometh as a thief in the night; for when they shall say, Peace and safety; then sudden destruction cometh upon them” (1 Thess. 5:2-32For yourselves know perfectly that the day of the Lord so cometh as a thief in the night. 3For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape. (1 Thessalonians 5:2‑3)). “The day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up” (2 Pet. 3:1010But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up. (2 Peter 3:10)). This scene is followed by “THE DAY OF GOD” in 2 Peter 3:1212Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat? (2 Peter 3:12), which ushers in the new heavens and the new earth.
It is important to keep the “day” quite distinct from the coming of the Lord to fetch His saints; for many have misapplied the term, and it has been constantly asserted that the Second Epistle to the Thessalonians was written to show the saints that it was wrong to be expecting the return of the Lord; whereas the fact is they thought the day of the Lord had come (though the First Epistle keeps the two things quite distinct (compare 1 Thess. 4:13-1813But I would not have you to be ignorant, brethren, concerning them which are asleep, that ye sorrow not, even as others which have no hope. 14For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him. 15For this we say unto you by the word of the Lord, that we which are alive and remain unto the coming of the Lord shall not prevent them which are asleep. 16For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: 17Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord. 18Wherefore comfort one another with these words. (1 Thessalonians 4:13‑18) with 1 Thess. 5:1-41But of the times and the seasons, brethren, ye have no need that I write unto you. 2For yourselves know perfectly that the day of the Lord so cometh as a thief in the night. 3For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape. 4But ye, brethren, are not in darkness, that that day should overtake you as a thief. (1 Thessalonians 5:1‑4)), and this could not come until Antichrist was revealed. There will be judgments before the millennium, and there will be judgments after the millennium, so that we may regard the Day of the Lord as extending through the millennium: it will be “the Lord’s” day in contrast to “man’s” day.

From Anstey’s Doctrinal Definitions:

This is an Old Testament term (Isa. 2:12,12For the day of the Lord of hosts shall be upon every one that is proud and lofty, and upon every one that is lifted up; and he shall be brought low: (Isaiah 2:12) etc.) used in the New Testament to indicate the time when the Lord’s authority will be publicly established on earth (1 Thess. 5:2, 42For yourselves know perfectly that the day of the Lord so cometh as a thief in the night. (1 Thessalonians 5:2)
4But ye, brethren, are not in darkness, that that day should overtake you as a thief. (1 Thessalonians 5:4); 2 Thess. 2:2-32That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand. 3Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition; (2 Thessalonians 2:2‑3) – J. N. Darby Trans.; Luke 21:3434And take heed to yourselves, lest at any time your hearts be overcharged with surfeiting, and drunkenness, and cares of this life, and so that day come upon you unawares. (Luke 21:34)). (It is not “the Lord’s day,” which is the first day of the week – Revelation 1:1010I was in the Spirit on the Lord's day, and heard behind me a great voice, as of a trumpet, (Revelation 1:10)). “The day of the Lord” will begin at the Appearing of Christ and will continue through the Millennium (2 Peter 3:8-108But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day. 9The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance. 10But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up. (2 Peter 3:8‑10)). Thus, it will last 1000 years. God has appointed this “day” at which time Christ will “judge the world in righteousness” (Acts 17:3131Because he hath appointed a day, in the which he will judge the world in righteousness by that man whom he hath ordained; whereof he hath given assurance unto all men, in that he hath raised him from the dead. (Acts 17:31)). The Lord will publicly intervene upon the ways of man on earth with His warrior judgments (Isa. 30:27-3327Behold, the name of the Lord cometh from far, burning with his anger, and the burden thereof is heavy: his lips are full of indignation, and his tongue as a devouring fire: 28And his breath, as an overflowing stream, shall reach to the midst of the neck, to sift the nations with the sieve of vanity: and there shall be a bridle in the jaws of the people, causing them to err. 29Ye shall have a song, as in the night when a holy solemnity is kept; and gladness of heart, as when one goeth with a pipe to come into the mountain of the Lord, to the mighty One of Israel. 30And the Lord shall cause his glorious voice to be heard, and shall show the lighting down of his arm, with the indignation of his anger, and with the flame of a devouring fire, with scattering, and tempest, and hailstones. 31For through the voice of the Lord shall the Assyrian be beaten down, which smote with a rod. 32And in every place where the grounded staff shall pass, which the Lord shall lay upon him, it shall be with tabrets and harps: and in battles of shaking will he fight with it. 33For Tophet is ordained of old; yea, for the king it is prepared; he hath made it deep and large: the pile thereof is fire and much wood; the breath of the Lord, like a stream of brimstone, doth kindle it. (Isaiah 30:27‑33); Rev. 19:11-2111And I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness he doth judge and make war. 12His eyes were as a flame of fire, and on his head were many crowns; and he had a name written, that no man knew, but he himself. 13And he was clothed with a vesture dipped in blood: and his name is called The Word of God. 14And the armies which were in heaven followed him upon white horses, clothed in fine linen, white and clean. 15And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God. 16And he hath on his vesture and on his thigh a name written, KING OF KINGS, AND LORD OF LORDS. 17And I saw an angel standing in the sun; and he cried with a loud voice, saying to all the fowls that fly in the midst of heaven, Come and gather yourselves together unto the supper of the great God; 18That ye may eat the flesh of kings, and the flesh of captains, and the flesh of mighty men, and the flesh of horses, and of them that sit on them, and the flesh of all men, both free and bond, both small and great. 19And I saw the beast, and the kings of the earth, and their armies, gathered together to make war against him that sat on the horse, and against his army. 20And the beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone. 21And the remnant were slain with the sword of him that sat upon the horse, which sword proceeded out of his mouth: and all the fowls were filled with their flesh. (Revelation 19:11‑21); Isa. 63:1-61Who is this that cometh from Edom, with dyed garments from Bozrah? this that is glorious in his apparel, travelling in the greatness of his strength? I that speak in righteousness, mighty to save. 2Wherefore art thou red in thine apparel, and thy garments like him that treadeth in the winefat? 3I have trodden the winepress alone; and of the people there was none with me: for I will tread them in mine anger, and trample them in my fury; and their blood shall be sprinkled upon my garments, and I will stain all my raiment. 4For the day of vengeance is in mine heart, and the year of my redeemed is come. 5And I looked, and there was none to help; and I wondered that there was none to uphold: therefore mine own arm brought salvation unto me; and my fury, it upheld me. 6And I will tread down the people in mine anger, and make them drunk in my fury, and I will bring down their strength to the earth. (Isaiah 63:1‑6)), and then will proceed with His sessional judgment (Matt. 25:31-4031When the Son of man shall come in his glory, and all the holy angels with him, then shall he sit upon the throne of his glory: 32And before him shall be gathered all nations: and he shall separate them one from another, as a shepherd divideth his sheep from the goats: 33And he shall set the sheep on his right hand, but the goats on the left. 34Then shall the King say unto them on his right hand, Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world: 35For I was an hungred, and ye gave me meat: I was thirsty, and ye gave me drink: I was a stranger, and ye took me in: 36Naked, and ye clothed me: I was sick, and ye visited me: I was in prison, and ye came unto me. 37Then shall the righteous answer him, saying, Lord, when saw we thee an hungred, and fed thee? or thirsty, and gave thee drink? 38When saw we thee a stranger, and took thee in? or naked, and clothed thee? 39Or when saw we thee sick, or in prison, and came unto thee? 40And the King shall answer and say unto them, Verily I say unto you, Inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto me. (Matthew 25:31‑40)), and lastly with His millennial judgment (Psa. 101:3-73I will set no wicked thing before mine eyes: I hate the work of them that turn aside; it shall not cleave to me. 4A froward heart shall depart from me: I will not know a wicked person. 5Whoso privily slandereth his neighbor, him will I cut off: him that hath an high look and a proud heart will not I suffer. 6Mine eyes shall be upon the faithful of the land, that they may dwell with me: he that walketh in a perfect way, he shall serve me. 7He that worketh deceit shall not dwell within my house: he that telleth lies shall not tarry in my sight. (Psalm 101:3‑7); Zech. 5:1-41Then I turned, and lifted up mine eyes, and looked, and behold a flying roll. 2And he said unto me, What seest thou? And I answered, I see a flying roll; the length thereof is twenty cubits, and the breadth thereof ten cubits. 3Then said he unto me, This is the curse that goeth forth over the face of the whole earth: for every one that stealeth shall be cut off as on this side according to it; and every one that sweareth shall be cut off as on that side according to it. 4I will bring it forth, saith the Lord of hosts, and it shall enter into the house of the thief, and into the house of him that sweareth falsely by my name: and it shall remain in the midst of his house, and shall consume it with the timber thereof and the stones thereof. (Zechariah 5:1‑4)).
There are two things that signal that “the day of the Lord” is “at hand” (about to begin):
•  The revelation of “the man of sin” (the Antichrist) and the “falling away” of Christendom after his delusions in the Great Tribulation (2 Thess. 2:33Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition; (2 Thessalonians 2:3)).
•  The attack of the King of the North (the Assyrian) on the Jews who will be gathered back in their homeland at the end of the Great Tribulation (Joel 1:15; 2:1-1115Alas for the day! for the day of the Lord is at hand, and as a destruction from the Almighty shall it come. (Joel 1:15)
1Blow ye the trumpet in Zion, and sound an alarm in my holy mountain: let all the inhabitants of the land tremble: for the day of the Lord cometh, for it is nigh at hand; 2A day of darkness and of gloominess, a day of clouds and of thick darkness, as the morning spread upon the mountains: a great people and a strong; there hath not been ever the like, neither shall be any more after it, even to the years of many generations. 3A fire devoureth before them; and behind them a flame burneth: the land is as the garden of Eden before them, and behind them a desolate wilderness; yea, and nothing shall escape them. 4The appearance of them is as the appearance of horses; and as horsemen, so shall they run. 5Like the noise of chariots on the tops of mountains shall they leap, like the noise of a flame of fire that devoureth the stubble, as a strong people set in battle array. 6Before their face the people shall be much pained: all faces shall gather blackness. 7They shall run like mighty men; they shall climb the wall like men of war; and they shall march every one on his ways, and they shall not break their ranks: 8Neither shall one thrust another; they shall walk every one in his path: and when they fall upon the sword, they shall not be wounded. 9They shall run to and fro in the city; they shall run upon the wall, they shall climb up upon the houses; they shall enter in at the windows like a thief. 10The earth shall quake before them; the heavens shall tremble: the sun and the moon shall be dark, and the stars shall withdraw their shining: 11And the Lord shall utter his voice before his army: for his camp is very great: for he is strong that executeth his word: for the day of the Lord is great and very terrible; and who can abide it? (Joel 2:1‑11)).
“The day of the Lord” and “the day of Christ” refer to the same period of time (the Millennium); the former emphasizes the exercise of His judgment in the earth and the latter the display of His glory with the Church.
