For the purpose of this post I will use man know this is for woman also.
The functions of the spirit,the soul, and the body.
The body is the world-consciousness the soul is self-consciousness and the Spirit is the God-consciousness. There are five organs in the body which enables man to communicate with the physical world. This is why it is called world-consciousness. The soul comprises that part in man known as the intellect, which make man’s existence possible. The part of love generates affection toward other human beings or objects. Affections originate from the senses. All this are parts of man himself they form the personality of man we call this self-consciousness. The Spirit is the part which an communicates with a God, serves Him and understands his relationship with God. We call this a God-consciousness. Just as God dwells in the spirit, the self dwells in the soul, and the senses dwell in the body.
The soul is the meeting place here the spirit and the body join. Man communicates with God’s Spirit and the spiritual realm through the spirit and receives and expresses power and life in the spiritual realm through this spirit. He communicates with the outside world of senses through the body. The world and the body interact with one another. The soul lies in between those two worlds and belongs to these two worlds. On one hand it communicates with the spiritual realm through the spirit, one on the other hand it communicates with the physical world through our body.
The soul has the power of determination- it can make decisions concerning the things related to it in the environment and can choose or reject them. It is impossible for the spirit to control the body directly; it requires a medium. (for lack of another word) This medium is our soul, which was produced when the spirit touched the body. The soul is in between the spirit and the body. It binds the spirit and body together as one.
The spirit can rule over the body through the soul and subject it under God’s power. The body can also insure the spirit through the soul to love the world.
Among the three elements of man, the spirit is joined to a God and is the highest. The body is in contact with the material world and this is the lowest. In between the two is the soul. It takes as it’s nature the nature of the other two. As it becomes the linkage of the other two parts. Through the soul the two parts can fellowship with each other and work together. The function of the soul is to maintain the spirit and the body in their proper order so that they will not lose their proper relationship with one another. In this way, the body with is the lowest, will submit to the spirit, and the spirit, which is highest, will be able to control the body through the soul. The soul is definitely the chief element in man. The soul looks to the spirit for the supply with the latter has received from the Holy Spirit and communicates to the body what it has received so that the body may partake of the perfection of the Holy Spirit and becomes a spiritual body.
The Spirit= The Soul= The Body.
