LOL! When a person sins (verb) he commits sin (noun).
Actually, its the noun that leads to the verb and not vice versa.
We are not sinners (noun) because we sinned (verb),
we sinned because we are sinners. This causality is the foundation of Paul's exposition of the sin problem in the book of Romans.
He explained it especially carefully in Romans 5:12-19: We are sinners because of Adam's sin (verb: his disobedience in the Garden of Eden).
Jesus was different because he did not inherit the sinner's blood from Adam like all of us did. His blood came directly from his Father, that is why it necessitated the virgin birth. He could not have sinned (verb) because he did not possess the sinful nature (noun) that all of us inherited from Adam as a "free gift".
When Jesus died on the cross, he took our sinful nature (noun) and not our sinful actions (verb). It was our sinful nature that separated us from God. When Paul said we have died to sin, it is the nature he was referring to, and not the verb.
