True. What I'm getting at is, it's my understanding that in order to be a fleshly Israelite, one has to be a descendant of Abraham, thru his legitimate heir, Isaac (son of promise).
The book of Romans was still written to the Romans (I don't see where it says "to all Gentiles that shall ever live.) Same for the letter to the Corinthians, etc. Yet (I presume, graciously) you are applying those to yourself. You aren't a Roman and you aren't a Corinthian.
