The answer from God’s word:
“The work done in the last days brings everything to a close; that done in the Age of Law is of commencement; and that done in the Age of Grace is of redemption. As for the visions of the work in this entire six-thousand-year management plan, none can gain insight or understanding. Such visions have always remained mysteries. … The last days are merely the time in which all the work in the six-thousand-year management plan is revealed to you. This is the unveiling of the mystery. Such mystery can be unveiled by no man. No matter how great an understanding man has of the Bible, it remains nothing more than words, for man does not understand the substance of the Bible. When man reads the Bible, he may receive some truths, explain some words or scrutinize some famous passages and quotes, but he will never be able to extricate the meaning contained within those words, for all man sees are dead words, not the scenes of the work of Jehovah and Jesus, and man is unable to unravel the mystery of such work. Therefore, the mystery of the six-thousand-year management plan is the greatest mystery, the one most hidden and utterly inconceivable to man. None can directly understand the will of God, unless He Himself explains and opens up to man, otherwise, they will forever remain riddles to man and forever remain sealed mysteries. Never mind those in the religious world; if you were not told today, neither would you be able to understand. This work of six thousand years is more mysterious than all the prophecies of the prophets. It is the greatest mystery since creation, and no former prophet has ever been able to fathom it, for this mystery is only unraveled in the final age and has never before been revealed. …
… The work in the last days lays bare the work of Jehovah and Jesus and all mysteries not understood by man. This is done to reveal the destination and end of mankind and conclude all work of salvation among mankind. This stage of work in the last days brings everything to a close. All mysteries not understood by man must be unraveled to allow man to gain insight into such and have a clear understanding in their hearts. Only then can man be divided according to their kinds. Only after the six-thousand-year management plan has been completed will man come to understand the disposition of God in its entirety, for His management will then have come to an end.”
from “The Mystery of the Incarnation (4)”
“At the time, Jesus did much work that was incomprehensible to His disciples, and said much that people did not understand. This is because, at the time, He did not give explanation. Thus, several years after He departed, Matthew created His genealogy, and others also did much work that was of the will of man. Jesus did not come to perfect and gain man, but to do one stage of work: bringing forth the gospel of the kingdom of heaven and completing the work of the crucifixion—and so once Jesus was crucified, His work came to a complete end. But in the current stage—the work of conquest—more words must be spoken, more work must be done, and there must be many processes. So too must the mysteries of the work of Jesus and Jehovah be revealed, so that all people may have understanding and clarity in their belief, for this is the work of the last days, and the last days are the end of God’s work, the time of this work’s conclusion. … At the time, Jesus did much work that was incomprehensible to man. He departed quietly, and today there are still many who do not understand His words, whose understanding is erroneous yet still believed by them to be correct, who do not know that they are wrong. In the end, this current stage will bring God’s work to a complete end, and will provide its conclusion. All will come to understand and know of God’s management plan. The conceptions within man, his intentions, his erroneous understanding, his conceptions toward the work of Jehovah and Jesus, his views about the Gentiles, and all his absurdities will be corrected. And man will understand all the right paths of life, and all the work done by God, and the entire truth. When that happens, this stage of work will come to an end.”
from “The Vision of God’s Work (2)”
“The work I have been carrying out for thousands of years is only completely revealed to man in the last days. Only now have I opened up the full mystery of My management. Man knows the purpose of My work and moreover obtains an understanding of all My mysteries. And I have told man everything about the destination he has been concerned about. I have already uncovered for man all My mysteries that were hidden for over 5,900 years. Who is Jehovah? Who is the Messiah? Who is Jesus? You should know all these. The turns of My work lie in these names. Have you understood that?”
