All of these Scriptures are timing Messages for when Christ returns to gather His Church...
1Thes 5:1-7
1 But of the times and the seasons, brethren, ye have no need that I write unto you.
2 For yourselves know perfectly that the day of the Lord so cometh as a thief in the night.
3 For 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.
4 But ye, brethren, are not in darkness, that that day should overtake you as a thief.
5 Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness.
6 Therefore let us not sleep, as do others; but let us watch and be sober.
7 For they that sleep sleep in the night; and they that be drunken are drunken in the night.
(KJV)
2 Pet 3:10
10 But 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.
(KJV)
Rev 3:3
3 Remember therefore how thou hast received and heard, and hold fast, and repent. If therefore thou shalt not watch, I will come on thee as a thief, and thou shalt not know what hour I will come upon thee.
(KJV)
Rev 16:15
15 Behold, I come as a thief. Blessed is he that watcheth, and keepeth his garments, lest he walk naked, and they see his shame.
(KJV)
Not only is it Christ's coming that is "as a thief", but it's also "the day of The Lord" that occurs at the same time.
Isa 2:12-22
12 For 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:
13 And upon all the cedars of Lebanon, that are high and lifted up, and upon all the oaks of Bashan,
14 And upon all the high mountains, and upon all the hills that are lifted up,
15 And upon every high tower, and upon every fenced wall,
16 And upon all the ships of Tarshish, and upon all pleasant pictures.
17 And the loftiness of man shall be bowed down, and the haughtiness of men shall be made low: and the LORD alone shall be exalted in that day.
18 And the idols He shall utterly abolish.
19 And they shall go into the holes of the rocks, and into the caves of the earth, for fear of the LORD, and for the glory of his majesty, when he ariseth to shake terribly the earth.
20 In that day a man shall cast his idols of silver, and his idols of gold, which they made each one for himself to worship, to the moles and to the bats;
21 To go into the clefts of the rocks, and into the tops of the ragged rocks, for fear of the LORD, and for the glory of His majesty, when He ariseth to shake terribly the earth.
22 Cease ye from man, whose breath is in his nostrils: for wherein is he to be accounted of?
(KJV)
How is it that God's Word about that day of The Lord includes God's judgments upon the wicked, and the end of their wickedness, especially since the pre-trib rapture teaches Christ's Church being removed when Christ comes "as a thief" so wickedness can continue on the earth, i.e., the tribulation?
Joel 1:15
15 Alas for the day! for the day of the LORD is at hand, and as a destruction from the Almighty shall it come.
(KJV)
There's God's Testimony again of the day of The LORD coming with a destruction on the earth from God.
Joel 3:14-16
14 Multitudes, multitudes in the valley of decision: for the day of the LORD is near in the valley of decision.
15 The sun and the moon shall be darkened, and the stars shall withdraw their shining.
16 The LORD also shall roar out of Zion, and utter His voice from Jerusalem; and the heavens and the earth shall shake: but the LORD will be the hope of His people, and the strength of the children of Israel.
(KJV)
The earth is going to shake when The LORD comes to do that on that day of The LORD, which is when Paul and Peter said Christ comes "as a thief".
2 Cor 1:14
14 As also ye have acknowledged us in part, that we are your rejoicing, even as ye also are ours in the day of the Lord Jesus.
(KJV)
Phil 1:10
10 That ye may approve things that are excellent; that ye may be sincere and without offence till the day of Christ;
(KJV)
Phil 2:16
16 Holding forth the word of life; that I may rejoice in the day of Christ, that I have not run in vain, neither laboured in vain.
(KJV)
II Th 2:1-2
1 Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him,
2 That 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.
(KJV)
That "day of Christ" is the same "day of The LORD" in those above Scriptures. The 2 Thess.2:2 example is uniquely pointing to that day, because the Greek word for "Christ" in that verse is actually 'kurios' which means 'lord'.
