2Pe 3:3 Knowing this first, that there shall come in the last days scoffers,(and there are a few of those contributing to this thread) walking after their own lusts,
4 And saying, Where is the promise of his coming? for since the fathers fell asleep, all things continue as they were from the beginning of the creation.
5 For this they willingly are ignorant of, that by the word of God the heavens were of old, and the earth standing out of the water and in the water:
6 Whereby the world that then was, being overflowed with water, perished:
7 But the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men.
8 ¶ But, 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.
9 ¶ The 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.
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.(which part of this does not anyone understand?
11 ¶ Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness,
12 Looking 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?
That this day is coming, the Scriptures promise. When? We do not know. But Jesus said that if we watched for the signs, we would know enough to know when it was close. He does not want us to be ignorant. He wants us to be ready. He wants us to be sharing the gospel so that others will be saved and not destroyed when He comes. There are many more prophecies in scripture that have a direct relation to His second coming than to His first. Christ's second coming will be the end of 6000 years of rebellion and sin. Satan will not give up without a fight. Just as Satan has convinced many of his own non-existence, so has he convinced many that Jesus will either not return, is delayed, or His coming is something not to be concerned about. These are all lies.
We have no idea how cataclysmic will be these last days. But the Word does give us clues. The plagues of Egypt are a type of what is to come. What happened to Egypt is a mere shadow however of the global nature of the coming crisis. The Book of Revelation is not a myth or fairy tale to allegorised out of existence. It is a real final warning to all who would be saved.
The Book of Daniel is the OT counterpart to Revelation. They are to be studied together,; revelation cannot be ubderstood without first graspiong the truths and symbolic images of Daniel. They explain Revelation.
We are now living in the toes of the image of Daniel 2. The rock that is cut out that smites the feet of the image is ready to come. The harvest of the earth is ripe. The tares and the grain have been growing together now but the harvest will be reaped. The tares will be burnt and the grain gathered and taken to God's heaven.
Jesus said: Joh 14:2 In my Father’s house are many mansions: if it were not so, I would have told you. I go to prepare a place for you.
3 And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also.
After the earth and the things upon it are broken and destroyed at the second coming, the result is told to us by Jeremiah.
Jer 25:30 ¶ Therefore prophesy thou against them all these words, and say unto them, The LORD shall roar from on high, and utter his voice from his holy habitation; he shall mightily roar upon his habitation; he shall give a shout, as they that tread the grapes, against all the inhabitants of the earth.
31 A noise shall come even to the ends of the earth; for the LORD hath a controversy with the nations, he will plead with all flesh; he will give them that are wicked to the sword, saith the LORD.
32 Thus saith the LORD of hosts, Behold, evil shall go forth from nation to nation, and a great whirlwind shall be raised up from the coasts of the earth.
33 And the slain of the LORD shall be at that day from one end of the earth even unto the other end of the earth: they shall not be lamented, neither gathered, nor buried; they shall be dung upon the ground.
Jer 4:23 I beheld the earth, and, lo, it was without form, and void; and the heavens, and they had no light.
24 I beheld the mountains, and, lo, they trembled, and all the hills moved lightly.
25 I beheld, and, lo, there was no man, and all the birds of the heavens were fled.
26 I beheld, and, lo, the fruitful place was a wilderness, and all the cities thereof were broken down at the presence of the LORD, and by his fierce anger.
Isaiah had this to say:
Isa 11:4 But with righteousness shall he judge the poor, and reprove with equity for the meek of the earth: and he shall smite the earth with the rod of his mouth, and with the breath of his lips shall he slay the wicked.
also:
Isa 24:1 ¶ Behold, the LORD maketh the earth empty, and maketh it waste, and turneth it upside down, and scattereth abroad the inhabitants thereof....
...3 The land shall be utterly emptied, and utterly spoiled: for the LORD hath spoken this word.
...19 The earth is utterly broken down, the earth is clean dissolved, the earth is moved exceedingly.
20 The earth shall reel to and fro like a drunkard, and shall be removed like a cottage; and the transgression thereof shall be heavy upon it; and it shall fall, and not rise again.
While the earth is in this broken state, the saints are in heaven for 1000 years. At the end of the 1000 years the New Jerusalem comes down out of heaven , the heavens and the earth are made new, and eternity begins with God Himself making the earth the new capital of the universe and we shall riegn with Christ forever.
