The Apostle returns to a difficulty very similar to that which presented itself at the beginning of the chapter. The answer is couched under a slightly different metaphor. It is no longer death to the one, life to the other, but freedom from the one, service to the other. These are correlative terms. Freedom from sin implies service to God, just as freedom from God means service to sin. The same idea of service and freedom will be found worked out in John 8:32-34; John 8:36, and in Galatians 5:1.
