"The flesh" does not refer to the meat of our body, OR the soul within us. In Paul's useage, the "flesh" vs. the "spirit" refers to WHOM do we please. It goes back to Psalm 1. Which way will we go? Follow the passions of desire and the lower self, or follow the ways of God's Spirit, of obeying the commandments and loving others despite the inconvience it causes. Paul is asking us to follow the Spirit, not the Flesh, which has nothing to do with our meat or our soul. Our soul ALSO can choose the ways of the Spirit.
The soul is designed to direct the body, and the spirit is designed (originally in obedience to God) to direct the soul. When Satan told Eve that disobeying God she would not 'die', his lie was a parsing of what God had instructed the first couple ... Satan’s ploy was she would die in spirit (have a dead spirit) but not immediately in the flesh (the soul and body).
The soul directs the body for good or for evil. Paul tells us to follow the ways of the Spirit, meaning not our personal spirit, but God's Spirit within us. However, we can clearly use this same soul to direct our actions towards sin.
As for the comment regarding Job, perhaps you would like to reread the Book of Job ... God did not deliver Job for punishment due. Surely that was not your implied reasoning?
No, God didn't. God delivered Job to Satan for His own purposes. Certainly, God will deliver evil-doers to Satan for the man to realize, just as Job did, that God is supreme and God's ways are beyond our ways.
