For those who live according to the flesh set their minds on the things of the flesh, but those who live according to the Spirit set their minds on the things of the Spirit.  (Romans 8:5)

Having expounded on the doctrines of justification, sanctification and glorification, the apostle Paul now reaches a wonderful conclusion: for all who submit themselves to the authority of Jesus, there is no punishment, having been freed from prison of sin and death, which is the inevitable and inescapable fate of all humanity without divine intervention.

This means a new mindset, one that seeks to please Jesus as opposed to one set on self-gratification.  Paul’s Greek employs one noun, φρόνημα (phronéma) to cover the composite ‘mind-set’ of the translation (ESV) and it literally means being governed from within, impelled by personal insight, or more colloquially ‘going with your gut’.
