The answer from God’s word:
In His final work of concluding the age, God’s disposition is one of chastisement and judgment, which reveals all that is unrighteous, publicly judges all peoples, and perfects those who truly love Him. Only a disposition such as this can bring the age to an end. The last days have already arrived. All things will be classed according to their kind, and will be divided into different categories based on their nature. This is the time when God reveals people’s outcome and their destination. If people do not undergo chastisement and judgment, then there will be no way of revealing their disobedience and unrighteousness. Only through chastisement and judgment can the end of all things be revealed. Man only shows his true colors when he is chastised and judged. Evil shall return to evil, good shall return to good, and people shall be classified according to their kind. Through chastisement and judgment, the end of all things will be revealed, so that the evil will be punished and the good will be rewarded, and all people will become subject under the dominion of God. All the work must be achieved through righteous chastisement and judgment. Because man’s corruption has reached its peak and his disobedience has been too serious, only God’s righteous disposition, which is principally one of chastisement and judgment and is revealed during the last days, can fully transform and complete man. Only this disposition can expose evil and thus severely punish all the unrighteous.
from “The Vision of God’s Work (3)” in The Word Appears in the Flesh
No matter what the imaginings of man, the substance of God’s work cannot be altered. The imaginings of man are nothing but the constructs of man’s thoughts and come from the brain of man, summed up and pieced together from what man has seen and heard. Therefore I say, however brilliant the images conceived, they are still no more than a drawing and no substitute for the plan of God’s work. After all, all of man has been corrupted by Satan, so how can he then fathom the thoughts of God? …
… In the last days, Christ uses a variety of truths to teach man, reveal the essence of man, and dissect his words and deeds. These words comprise various truths, such as man’s duty, how man should obey God, how man should be loyal to God, how man ought to live out the normal humanity, as well as the wisdom and disposition of God, and so on. These words are all focused on the essence of man and his corrupt disposition. In particular, those words that reveal how man spurns God are spoken in regard to how man is an embodiment of Satan and an enemy force against God. When God does the work of judgment, He does not simply make clear the nature of man with just a few words, but carries out revelation, dealing, and pruning over the long term. Such manner of revelation, dealing, and pruning cannot be substituted with ordinary words but with the truth that man does not possess at all. Only such manner of work is deemed judgment; only through such judgment can man be persuaded, be thoroughly convinced into submission to God, and gain true knowledge of God. What the work of judgment brings about is man’s understanding of the true face of God and the truth about his rebelliousness. The work of judgment allows man to gain much understanding of the will of God, of the purpose of God’s work, and of the mysteries that could not be understood by man. It also allows man to recognize and know his corrupt substance and the roots of his corruption, as well as to discover the ugliness of man. These effects are all brought about by the work of judgment, for the substance of such work is actually the work of opening up the truth, way, and life of God to all those who have faith in Him. This work is the work of judgment done by God. … Those who come before God to be judged and have been purified shall forever live in the kingdom of God. …
from “Christ Does the Work of Judgment With the Truth” in The Word Appears in the Flesh
In the work of the last days, the word is mightier than the manifestation of signs and wonders, and the authority of the word surpasses that of signs and wonders. The word reveals all the corrupt dispositions in the heart of man. You are unable to recognize them on your own. When they are revealed to you through the word, you will naturally come to the realization; you will not be able to deny them, and you will be utterly convinced. Is this not the authority of the word? This is the result achieved by the present work of the word. … Before man was redeemed, many of Satan’s poisons were already planted within him. After thousands of years of Satan’s corruption, man already has within him a nature that resists God. Therefore, when man has been redeemed, it is nothing more than redemption, where man is bought at a high price, but the poisonous nature within has not been eliminated. Man that is so defiled must undergo a change before being worthy to serve God. Through this work of judgment and chastisement, man will fully come to know the filthy and corrupt substance within him, and he will be able to completely change and become clean. Only in this way can man be worthy to return before the throne of God. All the work done this day is so that man can be made clean and be changed; through judgment and chastisement by the word, as well as refinement, man can cast away his corruption and be made pure. Rather than deeming this stage of work to be that of salvation, it would be more apt to say it is the work of purification. In truth, this stage is that of conquest as well as the second stage of salvation. Man is gained by God through judgment and chastisement by the word; through the use of the word to refine, judge and disclose, all of the impurities, notions, motives, and individual hopes within man’s heart are completely revealed. Though man has been redeemed and forgiven of his sins, it is only considered as God not remembering the transgressions of man and not treating man in accordance with man’s transgressions. However, when man lives in the flesh and he has not been set free from sin, he can only continue to sin, endlessly revealing the corrupt satanic disposition. This is the life that man leads, an endless cycle of sin and forgiveness. The majority of men sin in the day only to confess in the evening. As such, even if the sin offering is forever effective for man, it would not be able to save man from sin. Only half the work of salvation has been completed, for man still has corrupt disposition. … It is not easy for man to become aware of his sins; man is unable to recognize his own deeply rooted nature. Only through judgment by the word can such effects be achieved. Only thus can man gradually be changed from that point onward. Man shouted thus in the past because man had no understanding of his original corrupt disposition. Such are the impurities within man. Throughout such a long period of judgment and chastisement, man lived in an atmosphere of tension. Was this not all achieved through the word? Did you not also cry out with a very loud voice prior to the trial of service-doers? Enter the kingdom! All those who accept this name shall enter into the kingdom! All shall partake of God! When the trial of service-doers came, you no longer cried. At first, all cried out, “God! Wherever You place me, I shall submit to being steered by You.” Upon reading the words of God, “Who will be My Paul?” man said, “I am willing!” Then he saw the words, “And what of the faith of Job?” So he said, “I am willing to take the faith of Job. God, please test me!” When the trial of service-doers came, he collapsed at once and almost could not stand up again. After that, the impurities in man’s heart gradually diminished. Was this not achieved through the word? So, what you have experienced in the present are results achieved through the word, even greater than that achieved through Jesus’ working of signs and wonders. …
… they would all submit to the voice, falling down without words of revelation, much like how Paul fell to the ground amid the light as he journeyed to Damascus. If God continued to work in this way, man would never be able to know his own corruption through judgment by the word and attain salvation. Only through becoming flesh can He personally deliver His words to the ears of all so that all who have ears can hear His words and receive His work of judgment by the word. Only such is the result achieved by His word, rather than the emergence of the Spirit frightening man into submission. Only through such practical and extraordinary work can the old disposition of man, hidden deep within for many years, be fully revealed so that man may recognize it and have it changed. This is the practical work of God incarnate; He speaks and executes judgment in a practical manner to achieve the results of judgment upon man by the word. This is the authority of God incarnate and the significance of God’s incarnation.
from “The Mystery of the Incarnation (4)” in The Word Appears in the Flesh
God is almighty. God has a practical side that people don’t see. People always think of God as impractical, unrealistic—they think that He just does any old thing He thinks up without any particular meaning. They think that the meaning in God’s eyes is just made up stuff—as if He just says whatever He wants to. People should know that within this is the truth. The way in which God works is meaningful, is bound by necessity and achieves the best effect. It is all done with regard to a specific purpose, meaning and plan. You think God’s work is all just done at random? He has an all-powerful aspect, but He also has a practical aspect. … No matter what stage of the work He is engaged in, He always works practically. It’s not as some believe, that God doesn’t think or speak and does whatever He feels like. He has wisdom and His being, this is His substance. In doing His work, He needs substance, wisdom and for all of His disposition to be revealed and issued forth for man to receive. He doesn’t work groundlessly. He speaks in a practical way, He does His work day-by-day….
from “One Must Know the Way in Which God Works” in Records of Christ’s Talks
With regard to His practical side, God incarnate endured much suffering in His thirty-three and a half years on earth, in the end being crucified until His blood ran dry. He endured the most terrible suffering but then was resurrected from death. His resurrection was God’s aspect of almightiness at work. He did not make any indication, or shed any blood or make it rain and say this was a sin offering. He didn’t do anything like that, but instead He personally became flesh to make contact with the whole of mankind and was nailed to the cross, so that mankind would know of this deed. By means of this deed, mankind came to know that God had redeemed them and this was proof that God had indeed saved man.
