III. On the Truth of the Incarnation
15. The conceptions of man are laid bare when the incarnate God officially does His work, because the normality and reality of the incarnate God is the antithesis of the vague and supernatural God in man’s imagination. The original conceptions of man can only be revealed through their contrast to the incarnate God. Without the comparison to the incarnate God, the conceptions of man could not be revealed; in other words, without the contrast of reality the vague things could not be revealed. No one is capable of using words to do this work, and no one is capable of articulating this work using words. Only God Himself can do His own work, and no one else can do this work on His behalf. No matter how rich the language of man is, he is incapable of articulating the reality and normality of God. Man can only know God more practically, and can only see Him more clearly, if God personally works among man and completely shows forth His image and His being. This effect cannot be achieved by any fleshly man. Of course, God’s Spirit is also incapable of achieving this effect. God can save corrupt man from the influence of Satan, but this work cannot be directly accomplished by the Spirit of God; rather, it can only be done by the flesh God’s Spirit wears, by God’s incarnate flesh. This flesh is man and also God, is a man possessed of normal humanity and also God possessed of full divinity. And so, even though this flesh is not the Spirit of God, and differs greatly from the Spirit, it is still the incarnate God Himself who saves man, who is the Spirit and also the flesh. No matter what He is called by, ultimately it is still God Himself who saves mankind. For the Spirit of God is indivisible from the flesh, and the work of the flesh is also the work of the Spirit of God; it is just that this work is not done using the identity of the Spirit, but is done using the identity of the flesh. Work that needs to be done directly by the Spirit does not require incarnation, and work that requires the flesh to do cannot be done directly by the Spirit, and can only be done by God incarnate. This is what is required for this work, and is what is required by corrupt mankind.
