In his letters to various churches, St Paul makes use of the categories of 'Flesh' and 'Spirit, representing two competing approaches to engaging life. 'Flesh' does not mean simply our physical bodies. It means the system of values, desires and priorities that dominate our decision making when survival is our primary motivation. 'Spirit', on the other hand, refers to the Spirit of Christ. This means putting into practice the values, desires and priorities we see in the life of Christ. The most remarkable thing is that following Jesus brings new life even to our mortal bodies!
