The Answer from God’s Word:
God being the greatest in all the universe, could He fully explain Himself using the image of a flesh? God puts on this flesh in order to do one stage of His work. There is no significance in particular in this image of the flesh, it bears no relation to the passing of ages, nor does it have anything to do with God’s disposition. Why did Jesus not allow the image of Him to remain? Why did He not let man paint His image so that it could be passed on to later generations? Why did He not allow people to acknowledge that His image was the image of God? … He becomes flesh only so that the Spirit may find an appropriate place to reside when doing His work, the better to achieve His work in the flesh—so that people can see His work, come into contact with His disposition, hear His words, and know the wonder of His work. His name represents His disposition, His work represents His identity, but He has never said that His appearance in the flesh represents His image; that is merely a notion of man. And so, the crucial aspects of the incarnation of God are His name, His work, His disposition, and His gender. These are used to represent His management in this age. His appearance in the flesh bears no relation to His management, being merely for the sake of His work at the time. Yet it is impossible for God incarnate to have no particular appearance, and so He chooses the appropriate family to determine His appearance. If the appearance of God were to have representative significance, then all those who possess facial features similar to His would also represent God. Wouldn’t that be an egregious mistake? … God is Spirit, and man will never be capable of encompassing what His image is in the final analysis. His image can only be represented by His disposition. … Nor can you use the language of mankind to fully epitomize the image of God, for God is too exalted, too great, too wondrous and unfathomable!
from “The Vision of God’s Work (3)” in The Word Appears in the Flesh
It is imperative that God’s incarnate flesh should depart the earth upon completion of the work that He needs to do, for He comes only to do the work He ought to do, and not to show people His image. Even though the significance of the incarnation has already been fulfilled by God twice becoming flesh, still He will not openly manifest Himself to any nation that has never before seen Him. Jesus will never again show Himself to the Jews as the Sun of righteousness, nor will He ascend the Mount of Olives and appear to all peoples; all that the Jews have seen is the portrait of Jesus during His time in Judea. This is because the work of Jesus in His incarnation ended two thousand years ago; He will not return to Judea in His previous image, much less show Himself in His image from His time in Judea to any of the Gentile nations, for the image of Jesus become flesh is merely the image of a Jew, and not the image of the Son of man that John saw. Even though Jesus promised His followers that He would come again, He will not simply show Himself in the image of a Jew to all those in Gentile nations. … In the same way, the image of Jesus as a Jew can represent only the image of God as He worked in Judea, and He could only do the work of crucifixion. During the period when Jesus was in the flesh, He could not do the work of bringing the age to an end or destroying mankind. Therefore, after He had finished being crucified and concluded His work, He ascended on high and forever concealed Himself from man. From then on, those faithful believers from the Gentile nations were unable to see the manifestation of the Lord Jesus, but only the portrait of Him that they had pasted on the wall. This portrait is but one drawn by man, and not the image that God Himself showed to man. God will not openly show Himself to the multitude in the image from when He twice became flesh. The work He does among mankind is to allow them to understand His disposition. All this is shown to man by means of the work of the different ages; it is accomplished through the disposition He has made known and the work that He has done, rather than through the manifestation of Jesus. That is to say, the image of God is made known to man not through the incarnate image, but rather through the work carried out by the incarnate God who has both image and form; and through His (Her) work, His image is shown and His disposition is made known. This is the significance of the work He wishes to do in the flesh.
from “The Mystery of the Incarnation (2)” in The Word Appears in the Flesh
Jesus and I come from one Spirit. Even though We are unrelated in Our fleshes, Our Spirits are one; even though the content of what We do and the work that We take on are not the same, We are alike in essence; Our fleshes take different forms, but this is due to the change in era and the differing requirements of Our work; Our ministries are not alike, so the work We bring forth and the disposition We reveal to man are also different. That is why what man sees and understands this day is unlike that of the past; this is so because of the change in era. For all that They are different in the gender and the form of Their fleshes, and that They were not born of the same family, still less in the same time period, Their Spirits are nonetheless one. For all that Their fleshes share neither blood nor physical kinship of any kind, it cannot be denied that They are the incarnation of God in two different time periods. That They are the incarnate fleshes of God is an irrefutable truth, even though They are not of the same bloodline and do not share a common human language (one was a male who spoke the language of the Jews and the other a female who exclusively speaks Chinese). It is for these reasons that They have lived in different countries to do the work that it behooves each one to do, and in different time periods too. Despite the fact that They are the same Spirit, possessed of the same essence, there are no absolute similarities at all between the outward shells of Their fleshes. All They share is the same humanity, but as far as external appearance of Their fleshes and the circumstances of Their birth are concerned, They are not alike. These things have no impact on Their respective work or on the knowledge that man has of Them, for, in the final analysis, They are the same Spirit and none can separate Them. Even though They are not related by blood, Their entire beings are in the charge of Their Spirits, which allocates to Them different work in different time periods, and Their fleshes to different bloodlines. Similarly, the Spirit of Jehovah is not the father of the Spirit of Jesus, and the Spirit of Jesus is not the son of the Spirit of Jehovah: They are one and the same Spirit. Just like the incarnate God of today and Jesus. Though They are not related by blood, They are one; this is because Their Spirits are one. God can do the work of mercy and lovingkindness, as well as that of the righteous judgment and of chastisement of man, and that of calling down curses on man; and in the end, He can do the work of destroying the world and punishing the wicked. Does He not do all of this Himself? Is this not the omnipotence of God?
