What is the relationship between faith and obedience in the Reformed perspective?

From a Reformed viewpoint, faith and obedience cannot be separated. Romans 1:5 indicates that obedience comes from the faith that God grants, which emphasizes the transformative power of saving faith. This obedience is not a means of achieving salvation but a response to the grace already received through Christ. True faith manifests itself in a life that seeks to honor God’s commands as an expression of gratitude. Thus, the relationship is one of cause and effect: genuine faith produces the fruit of obedience, while disobedience reveals a lack of authentic faith, as illustrated in the preaching of the gospel which calls for this obedience rooted in Christ (Romans 1:8).
