This flesh is so important to mankind because He is man and even more God, because He can do the work that no ordinary man of flesh can do, and because He can save corrupt man, who lives together with Him on earth. Though He is identical to man, the incarnate God is more important to mankind than any person of value, for He can do the work that cannot be done by the Spirit of God, is more able than the Spirit of God to bear testimony to
God Himself, and is more able than the Spirit of God to fully gain mankind. As a result, although this flesh is normal and ordinary, His contribution to mankind and His significance to the existence of mankind make Him highly precious, and the real value and significance of this flesh is immeasurable to any man. Although this flesh cannot directly destroy Satan, He can use His work to conquer mankind and defeat Satan, and make Satan fully submit to His dominion. It is because God is incarnated that He can defeat Satan and is able to save mankind. He does not directly destroy Satan, but becomes flesh to do the work to conquer mankind, who has been corrupted by Satan. In this way, He is better able to bear testimony to Himself among the creatures, and is better able to save corrupted man. God incarnate’s defeat of Satan bears greater testimony, and is more persuasive, than the direct destruction of Satan by the Spirit of God. God in the flesh is better able to help man know the Creator, and is better able to bear testimony to Himself among the creatures.
