At the top of the thread, you cite scripture that suggests wars, famines, pestilences, earthquakes and all manner of calamity as the signal of the times of the end.
Now you cite scriptures suggesting that eating, drinking, buying, selling, planting, building -- the complete opposite -- will be the signal of the end.
What do you suppose this means?
JESUS in His Omniscience revealed that the people of the current time of the END of this world of Devil, and time of His coming, they would be like the people of Sodom, and Gomorrah and neighbouring cities.
So. "Likewise also as it was in the days of Lot; they did eat, they drank, they bought, they sold, they planted, they builded; the people of the current time of the END of this world of Devil do the same things. In fact, they did even worse than that: Genesis 13:v. 13 - Check it out.
But the same day that Lot went out of Sodom it rained FIRE(1Cor.3:v.13) and brimstone from heaven (heaven? Ephesians 1:v.3) , and destroyed them all". Remember: The testimony of JESUS is the Spirit of prophecy. Revelation 19:v.10
The FIRE is the Word, the Word is God, understand? The message of the Word -God- for the people of current time, for all the nations, is: We will destroy this world of Devil with all its nations, it will rain FIRE and brimstone from heaven, and will destroy them all", through all kind of punishments, as plagues, famines, earthquakes, nations against nations, and so on.
As was prophesied by Isaiah quoted above -verse 4 - , ... all the host of heaven shall be DISSOLVED(read 2 Peter 3:v.7and 11-15), and the heavens shall be rolled together as a scroll: and all their host shall fall down, as the leaf falleth off from the vine, and as a falling fig from the fig tree.
5 For my Sword shall be bathed in heaven: behold, it shall come down upon Edom, and upon the people of my CURSE, to Judgment.
6 The Sword of the Lord is filled with blood, it is made fat with fatness, and with the blood of lambs and goats, with the fat of the kidneys of rams: for the Lord hath a sacrifice in Bozrah, and a great slaughter in the land of Edom.
8 For it is the Day of the Lord's vengeance, and the year of recompences for the controversy of Zion.
Revelation 11:v.15 to 18 combined with the message above:
15 And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms OF THIS WORLD are become the kingdoms of our Lord, and of His Christ; and He shall reign for ever and ever.
16 And the four and twenty elders, which sat before God on their seats, fell upon their faces, and worshipped God,
17 Saying, We give thee thanks, O Lord God Almighty, which art, and wast, and art to come; because thou hast taken to thee thy great power, and hast reigned.
18 And the nations were (will be angry), and thy wrath is come, and the time of the dead, that they should be judged, and that thou shouldest give reward unto thy servants the prophets, and to the saints, and them that fear thy name, small and great; and shouldest destroy them which destroy the earth.
