The answer from God’s word:
“God created this world, He created this mankind, and moreover He was the architect of ancient Greek culture and human civilization. Only God consoles this mankind, and only God cares for this mankind night and day. Human development and progress is inseparable from the sovereignty of God, and the history and future of mankind are inextricable from the designs of God. If you are a true Christian, then you will surely believe that the rise and fall of any country or nation occurs according to the designs of God. God alone knows the fate of a country or nation, and God alone controls the course of this mankind. If mankind wishes to have a good fate, if a country wishes to have a good fate, then man must bow down to God in worship, repent and confess before God, or else the fate and destination of man will unavoidably end in catastrophe.
Look back to the time of Noah’s ark: Mankind was deeply corrupt, had strayed from the blessing of God, was no longer cared for by God, and had lost the promises of God. They lived in darkness, without the light of God. Thus they became licentious by nature, abandoned themselves to hideous depravity. Such men could no longer receive the promise of God; they were unfit to witness the face of God, nor to hear the voice of God, for they had abandoned God, had cast aside all that He had bestowed upon them, and had forgotten the teachings of God. Their heart strayed farther and farther from God, and as it did, they became depraved beyond all reason and humanity, and became increasingly evil. Thus they came ever closer to death, and fell under the wrath and punishment of God. Only Noah worshiped God and shunned evil, and so he was able to hear the voice of God, and hear the instructions of God. He built the ark according to the instructions of God’s word, and assembled all manner of living creatures. And in this way, once everything had been prepared, God unleashed His destruction upon the world. Only Noah and the seven members of his family survived the destruction, for Noah worshiped Jehovah and shunned evil.”

“When disaster comes, famine and plague will befall all those who oppose Me and they will weep. Those who have committed all kinds of evil during their many years as My follower shall not be guiltless; they too will live in a constant state of panic and fear amidst the disaster that has scarcely been seen through the ages. And all My followers who have been loyal to no other shall rejoice and applaud My might. They will experience ineffable contentment and live in a joy that I have never before bestowed upon mankind. For I treasure the good deeds of men and abhor their evil deeds. Since I first began to lead mankind, I have been hoping for a group of men who are of the same mind with Me. And I have never forgotten those not of the same mind; I have loathed them in My heart, awaiting only the opportunity to see My retribution administered on those wrongdoers and relish in such. My day has finally come and I need no longer wait!
My final work is not only to punish man but to arrange the destination of each. Moreover, it is to receive acknowledgement from all for all that I have done. I want each and every man to see that all I have done is in the right and is an expression of My disposition; it is not the doing of man, least of all nature, that brought forth mankind. On the contrary, it is I who nourish every living being among all things. Without My existence, mankind can only perish and suffer the invasion of plagues. None will ever again see the beauteous sun and moon or the green world; mankind shall encounter only the frigid night and the inexorable valley of the shadow of death. I am mankind’s only salvation. I am mankind’s only hope and even more, I am He on whom the existence of all mankind rests. Without Me, mankind will immediately become stagnant. Without Me, mankind will suffer catastrophe and be trod upon by all manner of ghosts, even though none take heed of Me. I have done work that can be done by no other only in the hope that man repay Me with good deeds. Though few can repay Me, I still conclude My journey in the world and begin on the work that will next unfold, for My journey among men these many years has been fruitful, and I am very pleased. I care not about the number of men but rather about their good deeds. In any case, I hope that you do sufficient good deeds in preparation for your own destination. Then will I be satisfied; otherwise, none of you shall escape the disaster. The disaster is brought down by Me and of course orchestrated by Me. If you cannot work for good in My presence, then you will not escape suffering the disaster.”

“All disasters befall one after another, and disasters arise in every nation and every place. Plagues, famines, floods, droughts, and earthquakes can be seen everywhere. They do not happen in one or two places, nor will they be over in one or two days, but they will spread over more and more regions. Moreover, the disasters will be greater and greater. During this period, various kinds of insect plagues will break out one after another, and cannibalism of man will occur in various places. All these are My judgment upon all nations and all peoples. My sons! You will surely be free from the sufferings and afflictions. I wish you to grow up soon so as to take up the burden on My shoulder earlier. Why do you not understand My heart’s desire? The work will be heavier and heavier in future. Could you bear to let Me alone work busily? Let Me put it more plainly: Whoever grows up in life will enter the refuge and be free from sufferings and afflictions; whoever fails to grow up in life will be bound to suffer and be afflicted. Haven’t I spoken about it plainly enough?”

“But know that I will not annihilate the entire world, nor will I annihilate the whole of mankind. I will keep that remaining third—the third that loves Me and has been thoroughly conquered by Me, and I will cause this third to be fruitful and multiply on earth just as the Israelites did under the law, nourishing them with copious sheep and cattle and all the riches of earth. This mankind will remain with Me forever, yet it is not the deplorably filthy mankind of today, but a mankind that is an assembly of all those who have been gained by Me. Such a mankind will not be damaged, disturbed, or besieged by Satan, and will be the only mankind that exists on earth after I have triumphed over Satan. It is the mankind that has today been conquered by Me and has gained My promise. And so, the mankind that has been conquered during the last days is also the mankind that will be spared and will gain My everlasting blessings. It will be the only evidence of My triumph over Satan, and the only spoils of My battle with Satan. These spoils of war are saved by Me from the domain of Satan, and are the only crystallization and fruit of My six-thousand-year management plan. They come from every nation and denomination, and every place and country throughout the universe. They are of different races, have different languages, customs and skin colors, and they are spread across every nation and denomination of the globe, and even every corner of the world. Eventually, they will come together to form a complete mankind, an assembly of man that is unreachable by the forces of Satan. Those among mankind who have not been saved and conquered by Me will sink silent to the depths of the sea, and will be burned by My consuming flames for all eternity. I will annihilate this old, supremely filthy mankind, just as I annihilated the firstborn sons and cattle of Egypt, leaving only the Israelites, who ate lamb’s meat, drank lamb’s blood, and marked their door lintels with lamb’s blood. Are the people who have been conquered by Me and are of My family not also the people who eat the meat of Me the Lamb and drink the blood of Me the Lamb, and have been redeemed by Me and worship Me? Are such people not always accompanied by My glory? Have not those who are without the meat of Me the Lamb already sunk silent to the depths of the sea?”
