Hunt describes the spiritual mind:
“Romans 8:6 gives us another adjective to apply to the spiritual mind: ‘The mind set on the Spirit is life and peace.’ The spiritual mind is peaceful. Paul had said in the previous verse, ‘Those who are according to the flesh set their minds on the things of the flesh, but those who are according to the Spirit, the things of the Spirit’ (Romans 8:5). Note again that we set our minds. Peace is a fruit, not an attainment. Our work is setting the mind; God’s work is the peace. Sin separates us from God, the source of peace.”
