I

The only reason that the incarnate God has come into the flesh is because of the needs of corrupt man. For those to be saved, the use value of the Spirit is far inferior to that of the flesh: The work of the Spirit can cover the entire universe, across all mountains, rivers, lakes, and oceans, yet the work of the flesh more effectively relates to every person with whom He comes into contact. What is more, God's flesh with tangible form can better be understood and trusted by man, and can further deepen man's knowledge of God, and is able to leave upon man a more profound impression of the practical deeds of God.

The work of the Spirit is shrouded in mystery; it is difficult for mortal beings to predict, and even harder for them to see, and so they can only rely on baseless imaginings. The work of the flesh, however, is normal and practical, and possessed of rich wisdom, and is a fact that can be personally seen by the eyes of mortal man; man can personally appreciate the wisdom of the work of God, and has no need to employ his bountiful imagination. This is the accuracy and practical value of the work of God in the flesh.

The Spirit can only do things that are invisible to man and difficult for him to imagine, but these things cannot provide any clear meaning. They can only provide a moving, or a roughly similar meaning, and cannot give an instruction with words. The work of God in the flesh, however, is greatly different: It involves the accurate guidance of words, and there are clear intentions and clear required goals to it. For corrupt people, only work that provides accurate words and clear goals to pursue, and is visible and tangible, is the most valuable kind of work. Only realistic work and timely guidance are suited to man's tastes, and only practical work can save man from his corrupt and depraved disposition. This can only be achieved by the incarnate God; only the incarnate God can save man from his old corrupt and depraved disposition.
