Those who live according to the sinful nature have their minds set on what that nature desires, but those who live in accordance with the Spirit have their minds set on what the Spirit desires.  The mind of sinful man is death, but the mind controlled by the Spirit is life and peace…

…have their mind set on what the Spirit desires

…the mind controlled by the Spirit is life and peace.  What does this mean – a Spirit controlled mind?  It means meeting the every day problems of life with the things of God, not the wisdom of the world or the responses of a sinful nature.

A person you work with rubs against you, exercise patience.  You and a friend are struggling with your relationship, remember to love one another as Christ  has  loved you.  Treated unfairly by someone in authority over you,  trust God for faithfulness and self-control.  These are the opportunities to practice the Christian life,  responding with holiness to the occasions of life in a fallen creation.
