The answer from God’s word:
“Since man believes in God, he must closely follow the footsteps of God, step-by-step; he should ‘follow the Lamb wherever He goes.’ Only these are the people who seek the true way, only they are the ones who know the work of the Holy Spirit. People who slavishly follow letters and doctrines are those who have been eliminated by the work of the Holy Spirit. In each period of time, God will begin new work, and in each period, there will be a new beginning among man. If man only abides by the truths that ‘Jehovah is God’ and ‘Jesus is Christ,’ which are truths that only apply to a single age, then man will never keep up with the work of the Holy Spirit, and will forever be incapable of gaining the work of the Holy Spirit. Regardless of how God works, man follows without the slightest doubt, and he follows closely. In this way, how could man be eliminated by the Holy Spirit? Regardless of what God does, as long as man is certain that it is the work of the Holy Spirit, and cooperates in the work of the Holy Spirit without any misgivings, and tries to meet the requirements of God, then how could he be punished? The work of God has never ceased, His footsteps have never halted, and prior to the completion of His work of management, He has always been busy, and never stops. But man is different: Having gained but a modicum of the Holy Spirit’s work, he treats it as if it will never change; having gained a little knowledge, he does not go forth to follow the footsteps of God’s newer work; having seen but a bit of God’s work, he immediately prescribes God as a particular wooden figure, and believes that God will always remain in this form that he sees before him, that it was like this in the past and will always be thus in the future; having gained but a superficial knowledge, man is so proud that he forgets himself and begins to wantonly proclaim the disposition and being of God that simply do not exist; and having fastened upon one stage of the Holy Spirit’s work, no matter what kind of person it is that proclaims the new work of God, man does not accept it. These are people who cannot accept the new work of the Holy Spirit; they are too conservative, and incapable of accepting new things. Such people are those who believe in God but also reject God. Man believes that the Israelites were wrong to ‘only believe in Jehovah and not believe in Jesus,’ yet the majority of people act out a role in which they ‘only believe in Jehovah and reject Jesus’ and ‘long for the return of the Messiah, but oppose the Messiah who is called Jesus.’ … Only those who follow the footsteps of the Lamb to the very end can gain the final blessing, whereas those clever people, who are unable to follow to the very end yet believe they have gained all, are incapable of witnessing the appearance of God. They all believe they are the smartest person on earth, and they cut short the continued development of God’s work for no reason at all, and seem to believe with absolute certainty that God will take them up to heaven, they who ‘have the utmost loyalty to God, follow God, and abide by the words of God.’ Even though they have the ‘utmost loyalty’ toward the words spoken by God, their words and actions still feel so disgusting because they oppose the work of the Holy Spirit, and commit trickery and evil. Those who do not follow to the very end, who do not keep up with the work of the Holy Spirit, and who only cleave to the old work have not only failed to achieve loyalty to God, but on the contrary, have become those who oppose God, have become those who are rejected by the new age, and who will be punished. Are there any more pitiable than them? Many even believe that all those who reject the old law and accept the new work are without conscience. These people, who only talk of conscience, and do not know the work of the Holy Spirit, will ultimately have their prospects cut short by their own consciences. God’s work does not abide by doctrine, and even though it is His own work, still God does not cling to it. That which should be denied is denied, that which should be eliminated is eliminated. Yet man places himself in enmity of God by holding onto but one small part of the work of God’s management. Is this not the absurdity of man? Is this not the ignorance of man? The more that people are timid and overcautious because they are afraid of not gaining God’s blessings, the more that they are incapable of gaining greater blessings, and of receiving the final blessing. Those people who slavishly abide by the law all display the utmost loyalty toward the law, and the more they display such loyalty toward the law, the more they are rebels who oppose God. For now is the Age of Kingdom and not the Age of Law, and the work of today cannot be held up against the work of the past, and the work of the past cannot be compared to the work of today. The work of God has changed, and the practice of man has also changed; it is not to hold onto the law or bear the cross. So, people’s loyalty toward the law and the cross will not gain God’s approval.”
from “God’s Work and Man’s Practice” in The Word Appears in the Flesh
“The old age has passed; now is a new age. And in a new age, new work must be done. Particularly in the final age where man will be perfected, God will perform new work ever more quickly. Therefore, without obedience in his heart, man will find it difficult to follow the footsteps of God. God abides not by the rules, nor does He treat any stage of His work as unchanging. Rather, the work done by God is ever newer and ever higher. His work becomes more and more practical with each step, more and more in line with the actual needs of man. Only after man experiences this kind of work can he attain the final transformation of his disposition. Man’s knowledge of life grows ever higher, therefore the work of God likewise becomes ever higher. Only in this way can man reach perfection and be fit for God’s use. On one hand, God works this way to counter and reverse the notions of man, while on the other, to lead man into a higher and more realistic state, into the highest realm of belief in God, so that in the end, the will of God is done. All those of a disobedient nature and with a heart of resistance shall be forsaken in this fast and powerful work; only those who have an obedient heart and are willing to be humbled will progress to the end of the road. In such work, all of you should learn how to submit and to put aside your notions. Every step should be taken with caution. If you are careless, you will surely become one of those loathed and rejected by the Holy Spirit and one who disrupts the work of God. Prior to undergoing this stage of work, man’s rules and laws of old were so innumerable that they got carried away, and as a result, they became conceited and forgot their place. These are all obstacles in the way of man accepting the new work of God and are hostile to man coming to know God. It is dangerous for man to have neither obedience in his heart nor a yearning for the truth. If you obey only the work and words that are simple, and are unable to accept any of a deeper intensity, then you are one who keeps to old ways and cannot keep pace with the work of the Holy Spirit. The work done by God differs across periods of time. If you show great obedience in one phase, yet in the next phase show less or none at all, then God shall desert you. If you keep pace with God as He ascends this step, then you must continue to keep pace when He ascends the next. Only such men are obedient to the Holy Spirit.”
