I

The first incarnation was to redeem man from sin, to redeem him by means of Jesus's fleshly body, that is, He saved man from the cross, but the corrupt satanic disposition still remained within man. The second incarnation is no longer to serve as a sin offering but rather to save fully those who were redeemed from sin. This is done so that those whose sins have been forgiven may be delivered from their sins and fully purified, and attain a changed disposition, and thus break free of Satan's dark influence and return before God's throne. Only in this way can man be fully sanctified.

II

Only by becoming flesh can God live alongside man, experience the suffering of the world, and live in a normal body of flesh. Only in this way can He supply men with the practical Word that they need as created beings. It is through the incarnation of God that man receives full salvation from God, and not directly from heaven in answer to his prayers. Man is of flesh and blood, he has no way of seeing the Spirit of God, much less of approaching His Spirit, so all that he can come into contact with is God's incarnate flesh. Only by means of this is man able to grasp all of the Word and all the truths and receive full salvation.

III

The second incarnation will be sufficient to purge away the sins of man and to fully purify him. Hence, with the second incarnation, the entirety of God's work in the flesh will be brought to a close and the significance of God's incarnation be made complete. Thenceforth, God's work in the flesh will have entirely come to an end. He won't become flesh a third time for His work. For His entire management will have come to an end, the incarnation of the last days will have fully gained the people He has selected, and mankind in the last days will all have been sorted according to their kind. He will no longer do the work of salvation, nor will He return to the flesh to carry out any work.
