Walk habitually in the Holy Spirit. Seek Him and be responsive to His guidance. When you do this, you will certainly not carry out the desire of the sinful nature. This responds impulsively without regard for God and His precepts.
Live freely, animated and motivated by God’s Spirit. Then you won’t feed the compulsions of selfishness. For there is a root of sinful self-interest in us that is at odds with a free spirit, just as the free spirit is incompatible with selfishness. These two ways of life are antithetical, so that you cannot live at times one way and at times another way according to how you feel on any given day.
