Ahhhh..but who are the "saints" and what is their "sacrifice"?
Rev 14:12 Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus.
Rev 12:17 And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ.
We know who the book of the covenant was given to in Exodus 24. Yes, I believe they are the lost tribes of Israel. They are out there somewhere and they will at some point in the future be gathered back together through Christ to help restore order in this earth. I don't believe they would keep the sacrificial law today as they did in old times since Christ took it away. Also, I don't believe the Levites would be trying to operate under the Levitical priesthood as they did since they would learn that Christ is now Priest. They would however, continue observing their HolyDays and eating only clean foods. We know many of them are scattered and have no idea who they are since it was prophesied they'd loose their heritage.
Also, some additional passages to examine regarding these people:
Deu 7:6 For thou art an holy people unto the LORD thy God: the LORD thy God hath chosen thee to be a special people unto himself, above all people that are upon the face of the earth.
Psa 147:19 He sheweth his word unto Jacob, his statutes and his judgments unto Israel.
Psa 147:20 He hath not dealt so with any nation: and as for his judgments, they have not known them. Praise ye the LORD.
But in context to the precepts I mentioned earlier, while we are all saints if we follow Christ as the scripture saith , we should examine any individuals claiming to be of the lost tribes to see if they fit the curses. If they can prove they fit the curses, that's who we should go to for understanding on prophecies/mysteries ( . ) If you're being taught by any other individuals, if they themselves have not been taught by them, you run the risk of being told a lie. That is my belief regarding the topic of the matter. So at this time I've decided to focus my attention to anyone claiming to be of Israel. With that, I'm also examining who is suffering in this earth today. Tribe attributes and curses such as Malachi 2:3 along with just gaining knowledge on the history of all nations on this earth to see if there are any inconsistencies. These are some areas I've decided to devote my time towards while checking everything back to the bible to see if it lines up with scriptures and prophecy. Hope you all have a blessed study. Be diligent in your search for truth. Stay encouraged.

Mat 7:21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
