Welcome Sunshine. You should do a search on the site and in Ray's papers because he discusses this issue a lot. But I will briefly tell you that most of us here think of the holy days and sabbaths as being spiritual and don't physically keep them -- along with Christmas and Easter I might add.
Ray has written lots on this subject with all the scriptural support.

Seeking out the truth about the Sabbath was actually what led me to Ray's site a few years ago as I had a very close friend who was Seventh Day Adventist. She passed away a few months ago. Ray recently taught on keeping the Sabbath and you can find the audio to that here:

And the Holy Days and offerings are full of revelation and meaning -- but spiritual. You don't have to literally celebrate these Holy Days any more than you need to slaughter a bullock for sacrifice.
Welcome again to our forum.
