What does being 'sold under sin' mean?

In Romans 7:14, Paul states, 'For we know that the law is spiritual: but I am carnal, sold under sin.' This phrase encapsulates the concept of humanity's innate bondage to sin, illustrating that every individual is born with a sinful nature that leads them to sin without restraint. This state of being 'sold under sin' signifies a lack of freedom to choose righteousness and reveals the desperate need for the redemptive work of Christ. Understanding this bondage is pivotal; it clarifies that true freedom comes only through salvation and deliverance granted by Jesus Christ, further underpinning the Reformed doctrine that emphasizes sin's totality and the necessity of divine grace for true liberation.
