1. God’s first incarnation was to redeem man from sin through the flesh of Jesus, 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 to fully save those who were redeemed from sin. This is done so that those forgiven can be delivered from their sins and be fully made clean, and attain a change in disposition, thereby breaking free of Satan’s influence of darkness and returning before the throne of God. Only in this way can man be fully sanctified.
2. Only if God becomes flesh can He live alongside man, experience the suffering of the world, and live in an ordinary flesh. Only in this way can He supply man of His creation with the practical word that they need. Man receives full salvation from God because of God incarnate, not directly from their prayers to heaven, not directly from their prayers to heaven. For man is fleshly; man is unable to see the Spirit of God and much less able to approach Him. All that man can associate with is God’s incarnate flesh; only through Him can man understand all the words and all the truths, and receive full salvation.
3. The second incarnation is sufficient to get rid of the sins of man and fully purify man. Hence, the second incarnation will bring to a close all the work of God in the flesh and complete the significance of God’s incarnation. Thereafter, the work of God in the flesh will have entirely come to an end. After the second incarnation, He will not again become flesh for His work. For His entire management will have come to an end. In the last days, His incarnation will have fully gained His chosen people, and all man in the last days will have been divided according to their kind. He will no longer do the work of salvation, nor will He return to flesh to carry out any work.
