The day of the Lord has nothing to do with the Sabbath day. It appears to me that "The Day of the Lord" is about the return of Christ. "For yourselves know perfectly that "The Day of the Lord" so comes as a thief in the night" 1 Thessalonians 5:2.
And then Peter wrote,"But "The Day of the Lord" will come as a thief in the night; in 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.
Even some of the Old Testament prophets spoke of "The Day of the Lord" "Alas for "The Day of the Lord" is at hand, and as a destruction from the almighty shall it come" Joel 1:15.
Isaiah the prophet said, "For "The Day of the Lord" of host shall be upon everyone that is proud and lofty, and upon everyone that is lifted up; and he shall be brought low" Isaiah 2:12.
"Neither their silver nor their gold shall be able to deliver them in "The Day of the Lord's" wrath ; but the whole land shall be devoured by the fire of his jealousy: for he shall make even a speedy riddance of all of them that dwell in the land" Zephaniah 1:18.
These scriptures speak of the judgment that Jesus will execute when he returns. We must assume that "The Day of the Lord" is the day of judgment. No one likes to talk about judgment, especially the unsaved, God is a God of judgment. If he didn't judge he would not be holy and righteous. His judgments are perfect and complete, unlike the judgments of men.
When Jesus appears in the Eastern sky all that are not "In Christ" will wail because of him, Revelation 1:7. All that have rejected him and his Gospel, will hide in caves and call for the rocks to fall on them, "For the great day of his wrath is come; and who shall be able to stand?"
Revelation 6:16, 17. Only those that are "In Christ" will be able to stand, not only will they stand they will be caught up to be with him, Colossians 3:4.
