The Man...

Man is a tripartite being: spirit, soul, and body. The body is that part of our being that gets information from the world and relates back to it. This it does through our five senses: the sense of sight, touch, taste, hearing and smell. The flesh has a nature which is to do its will. The human flesh is also lazy and domineering. The desires of the body are contrary to the will of God. This therefore makes it impossible to please God in your body as a Christian. God gave us the body that He might have expression on the earth through us. However, God will only use those that are completely yielded to Him.                

For you to be used by God you must mortify your body. To mortify the body is to suppress its expression. There are two things you must do to mortify the body: first of all you must acknowledge that you died in Christ.  To acknowledge that death is to appreciate the death of Jesus Christ in a way that reflects your gratitude.  The acknowledgment that you are dead to sin will put a restrain to what you do with your body. The second thing to do is to commit yourself to God. By committing yourself to God you are asking for help. You cannot subdue the body with physical will power. You need the help of God to conquer the flesh. When the grace of God is released over your life, sin will no longer have power over you. You will be able to glorify God in your body by living in accordance with His will.
