Do you not know, brothers and sisters – for I am speaking to those who know the law

Do you not know, brothers and sisters – for I am speaking to those who know the law – that the law is binding on a person only during that person’s lifetime? Thus a married woman is bound by the law to her husband as long as he lives; but if her husband dies, she is discharged from the law concerning the husband.
I was once alive apart from the law, but when the commandment came, sin revived and I died, and the very commandment that promised life proved to be death to me. For sin, seizing an opportunity in the commandment, deceived me and through it killed me. So the law is holy, and the commandment is holy and just and good.
Did what is good, then, bring death to me? By no means! It was sin, working death in me through what is good, in order that sin might be shown to be sin, and through the commandment might become sinful beyond measure.
For we know that the law is spiritual; but I am of the flesh, sold into slavery under sin. I do not understand my own actions. For I do not do what I want, but I do the very thing I hate. Now if I do what I do not want, I agree that the law is good. But in fact it is no longer I that do it, but sin that dwells within me. For I know that nothing good dwells within me, that is, in my flesh. I can will what is right, but I cannot do it.
