Going back over the post on here, I found your. As I know I have not replied to it, I wish to do so now.
Though I can say you are right o some extent, I must ask. If every one of HaShems Laws are ment for every person on earth, why did He take teh time to make it clear what Laws are intended for every walk of life. The Priest have one set, the High priest another, Women yet another, There are laws for farmers, as well as teachers. This can go on and on, until I named every line of work, every walk of life, and ever stage of life. So when a person says that law is not for me, are doing so to keep from having to follow it, or is it that the law really is for another walk of life?
I can speak for everyone, Though I do know many other than my self that do follow the Shabbot, as it is given in Torah. Some of us even go so fare as to keep, Shmita. even outside Eretz Yisrael.
One thing you miss understand, as do most Law experts, is that the Law was not, is not, and never will be, a physical act. It was, is, and will always be, a spiritual act for them that keep it. Though this can only become true in the hearts of people that truly understand it, and don't try to place the whole of the law on a people that do it was not meant for. It was never meat to be what many think of today, as most only get a look at it, and then hear about Rabbinic Law, then add the 2 together.
This is often seen in many teachings. I won't go naming doctrines, or running them down, that simply is not right. Yet if one walks in to a church or meeting place, and finds they are faced with ritual, and not true study, or a mix of both. They may wish to remove them self.
