A.T. Robertson Commentary Romans 7:14

"For we know that the law is spiritual: but I am carnal, sold under sin." — Romans 7:14 (ASV)

Spiritual (πνευματικος). Spirit-caused and spirit-given and like the Holy Spirit. See 1 Corinthians 10:3f.

But I am carnal (εγω δε σαρκινος ειμ). "Fleshen" as in 1 Corinthians 3:1 which see, more emphatic even than σαρκικος," a creature of flesh."

Sold under sin (πεπραμενος υπο την αμαρτιαν). Perfect passive participle of πιπρασκω, old verb, to sell. See on Mt 13:46; Acts 2:45, state of completion. Sin has closed the mortgage and owns its slave.
