The Apostle Peter was writing to believers, not non-believers. He gave this warning to the Church:
Above all, you must understand that in the last days scoffers will come, scoffing and following their own evil desires. They will say, “Where is this ‘coming’ he promised? Ever since our ancestors died, everything goes on as it has since the beginning of creation.” But they deliberately forget that long ago by God’s word the heavens came into being and the earth was formed out of water and by water. By these waters also the world of that time was deluged and destroyed. By the same word the present heavens and earth are reserved for fire, being kept for the day of judgment and destruction of the ungodly.
But do not forget this one thing, dear friends: With the Lord a day is like a thousand years, and a thousand years are like a day. The Lord is not slow in keeping his promise, as some understand slowness. Instead he is patient with you, not wanting anyone to perish, but everyone to come to repentance.
But the day of the Lord will come like a thief. The heavens will disappear with a roar; the elements will be destroyed by fire, and the earth and everything done in it will be laid bare.
Since everything will be destroyed in this way, what kind of people ought you to be? You ought to live holy and godly lives as you look forward to the day of God and speed its coming. That day will bring about the destruction of the heavens by fire, and the elements will melt in the heat. But in keeping with his promise we are looking forward to a new heaven and a new earth, where righteousness dwells. (2 Peter 3;1-13)
Peter was writing about God’s promise. The promise to the Church was not about destruction, but about rescuing His people from destruction. The rapture of the Church and the Day of the Lord are two separate events.
Will Christians experience this destruction on earth? The Apostle Paul writes:
Behold, I tell you a mystery: We shall not all sleep, but we shall all be changed — in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised incorruptible, and we shall be changed. For this corruptible must put on incorruption, and this mortal must put on immortality. (1 Corinthians 15:51-53)
When Paul uses the term “sleep” he means that not all will die. There will be a time when true believers will immediately be changed from a corruptible body into a heavenly body. When will this take place? We will not know the day of the destruction of the earth, but we will be told about the day we escape destruction if we are listening. Paul writes:
But I do not want you to be ignorant, brethren, concerning those who have fallen asleep, lest you sorrow as others who have no hope. For if we believe that Jesus died and rose again, even so God will bring with Him those who sleep in Jesus.
For this we say to you by the word of the Lord, that we who are alive and remain until the coming of the Lord will by no means precede those who are asleep. For the Lord Himself will descend from heaven with a shout, with the voice of an archangel, and with the trumpet of God. And the dead in Christ will rise first. Then we who are alive and remain shall be caught up together with them in the clouds to meet the Lord in the air. And thus we shall always be with the Lord. Therefore comfort one another with these words. (1 Thessalonians 4:13-18)
Note that Paul writes that Christian believers should not be in the dark about the rapture:
But concerning the times and the seasons, brethren, you have no need that I should write to you. For you yourselves know perfectly that the day of the Lord so comes as a thief in the night. For when they say, “Peace and safety!” then sudden destruction comes upon them, as labor pains upon a pregnant woman. And they shall not escape. But you, brethren, are not in darkness, so that this Day should overtake you as a thief. You are all sons of light and sons of the day. We are not of the night nor of darkness. (1 Thessalonians 5;1-5)
Many are losing heart and hope during this time. People realize that something is coming. They are not sure what it is or what they can do about it. They are not sure they will be able to escape what this doom might be. Christians should not lose heart. We should be looking up. Jesus taught His disciples:
“And there will be signs in the sun, in the moon, and in the stars; and on the earth distress of nations, with perplexity, the sea and the waves roaring; men’s hearts failing them from fear and the expectation of those things which are coming on the earth, for the powers of the heavens will be shaken. Then they will see the Son of Man coming in a cloud with power and great glory. Now when these things begin to happen, look up and lift up your heads, because your redemption draws near.” (Luke 21:25-28)
For God has destined us not for wrath but for obtaining salvation through our Lord Jesus Christ, who died for us, so that whether we are awake or asleep we may live with him. Therefore encourage one another and build up each other, as indeed you are doing. (1 Thessalonians 5:9-11)
God will rescue His people from sudden destruction as He did with Lot in the Old Testament. He sent angles to take Lot and his family to safety:
When morning dawned, the angels urged Lot, saying, “Get up, take your wife and your two daughters who are here, or else you will be consumed in the punishment of the city.” But he lingered; so the men seized him and his wife and his two daughters by the hand, the Lord being merciful to him, and they brought him out and left him outside the city. When they had brought them outside, they said, “Flee for your life; do not look back or stop anywhere in the Plain; flee to the hills, or else you will be consumed.” (Genesis 19:15-17)
God rained sulfur and fire on Sodom and Gomorrah. We remember that Lot’s wife did not escape destruction because she held on to the world. Not everyone will be ready for the rapture. Jesus said:
“The days are coming when you will long to see one of the days of the Son of Man, and you will not see it. They will say to you, ‘Look there!’ or ‘Look here!’ Do not go, do not set off in pursuit. For as the lightning flashes and lights up the sky from one side to the other, so will the Son of Man be in his day. But first he must endure much suffering and be rejected by this generation. Just as it was in the days of Noah, so too it will be in the days of the Son of Man. They were eating and drinking, and marrying and being given in marriage, until the day Noah entered the ark, and the flood came and destroyed all of them. Likewise, just as it was in the days of Lot: they were eating and drinking, buying and selling, planting and building, but on the day that Lot left Sodom, it rained fire and sulfur from heaven and destroyed all of them — it will be like that on the day that the Son of Man is revealed. On that day, anyone on the housetop who has belongings in the house must not come down to take them away; and likewise anyone in the field must not turn back. Remember Lot’s wife. Those who try to make their life secure will lose it, but those who lose their life will keep it. I tell you, on that night there will be two in one bed; one will be taken and the other left. There will be two women grinding meal together; one will be taken and the other left. Two men will be in the field: the one will be taken and the other left.” (Luke 17:22-36)
God is warning us not to be unprepared:
“Behold, I am going to send My messenger, and he will clear the way before Me. And the Lord, whom you seek, will suddenly come to His temple; and the messenger of the covenant, in whom you delight, behold, He is coming,” says the Lord of hosts. “But who can endure the day of His coming? And who can stand when He appears? For He is like a refiner’s fire and like fullers’ soap. (Malachi 3:1-2)
“But take heed to yourselves, lest your hearts be weighed down with carousing, drunkenness, and cares of this life, and that Day come on you unexpectedly. For it will come as a snare on all those who dwell on the face of the whole earth. Watch therefore, and pray always that you may be counted worthy to escape all these things that will come to pass, and to stand before the Son of Man.” (Luke 21:34-36)
“And to the angel of the church in Sardis write: These are the words of him who has the seven spirits of God and the seven stars:
“I know your works; you have a name of being alive, but you are dead. Wake up, and strengthen what remains and is on the point of death, for I have not found your works perfect in the sight of my God. Remember then what you received and heard; obey it, and repent. If you do not wake up, I will come like a thief, and you will not know at what hour I will come to you. (Revelation 3:1-3)
How are we then to live?
The end of all things is near. Therefore be alert and of sober mind so that you may pray. Above all, love each other deeply, because love covers over a multitude of sins. Offer hospitality to one another without grumbling. Each of you should use whatever gift you have received to serve others, as faithful stewards of God’s grace in its various forms. If anyone speaks, they should do so as one who speaks the very words of God. If anyone serves, they should do so with the strength God provides, so that in all things God may be praised through Jesus Christ. To him be the glory and the power for ever and ever. Amen. (1 Peter 4:7-11)
Set your mind on things above, not on things on the earth. For you died, and your life is hidden with Christ in God. When Christ who is our life appears, then you also will appear with Him in glory.
Therefore put to death your members which are on the earth: fornication, uncleanness, passion, evil desire, and covetousness, which is idolatry. Because of these things the wrath of God is coming upon the sons of disobedience, in which you yourselves once walked when you lived in them.
But now you yourselves are to put off all these: anger, wrath, malice, blasphemy, filthy language out of your mouth. (Colossians 3:2-8)
Should we be in despair about all the end times signs? We can surely grieve for the world. We can pray for our lost relatives, friends, and neighbors. We can witness them. On the other hand, we need to lift up our heads:
And when these things begin to come to pass, then look up, and lift up your heads; for your redemption draweth nigh. (Luke 21:28)
Warning: The Rapture is near. Not all Christians will be raptured. We need a repentant heart, confessing our sins daily. Taking daily Communion is helpful. We must not hold any unforgiveness in our hearts. We must not commit any deliberate sin. We cannot be judging others. We should not have any attachments to this world, or even to families. Let us continue to pray for our family, friends, the lost, and those in danger of persecution, as well as ourselves.
