In this paragraph, Paul tells us how to move from the bondage of self-indulgence to the sphere of life in which human behaviour is totally controlled by spiritual love. The process is simple: "live by the Spirit and you will not satisfy the desires of the sinful nature" (verse 16). Following the apostolic mandate we find a graphic catalogue of behaviours that belong to the sinful nature (vv 19-21). The order is not significant, except that envy is underlined among these non-spiritual ways of life. What exactly is envy? Envy is a universal emotion. Everyone at some point feels envious under certain conditions. People sometimes envy good looks, a successful career, someone else's possessions, spiritual gifts, etc. However, for the person controlled by the sinful nature, envy has acquired an exaggerated dimension. The envious person seeks to devalue others to protect themselves from the internal pressure of their envy. This person despises others in order not to feel envious. Envy becomes for them a constant companion. Envy accompanies them to work, is present in social relationships and does not remain outside the place of worship. The envious person observes that another person knows more or does things better than he does, and feels a deep sense of anguish and jealousy. Envy poisons everyday life, prevents Christian love and hinders spiritual growth because the envious person is always concerned about what others do. Envy does not allow them to concentrate on the life of the Spirit. Let us be led by the Spirit and we will escape the compulsions of the sinful nature.
