James,

The word that is used for Private is idios from which we get idiotic.
Lots of people use that verse to say that anyone who does not go along with accepted theological views is using a "private interpretation.
The 7 heads are kings. The kings had their kingdom restored for an hour 83 years 4 months from 14 October 1929 through 14 February 2013.

The popes from Pius XI to Benedict XVI (who reigned a short space) and the 6th was Pope John-Paul II (who made war against Communism without firing a shot and received a deadly wound from which he recovered). The 8th is of the 7 John-Paul II. When Satan impersonates him ( Sunday sacredness and spiritualism will be the
focus of his impersonation.

What happened on 31 May 1998? Did I miss something.....

On May 31, 1998, Pope John Paul II issued a lengthy Pastoral Letter Dies Domini, a passionate plea for a revival of Sunday observance.
A significant event in the march to a Sunday law.

But not sure how that fits the "from the going forth of the commandment to restore and to build Jerusalem"
and how 69 weeks later Messiah the Prince comes.

All the reinterpretations of the time line prophecies are NOT where we should be ---
The 70 weeks began in 457 BC with a decree to restore Jerusalem, 69 weeks took us to Christ's baptism, and the last week ended in 34 AD with Stephen's covenant summons to the Jewish nation and his resulting martyrdom.

"New light" - George Bush is the 5th fallen king.

When time shall be no more, SDA, confronted by their dubious prognostications, will bow their head in shame. In that day, they will cry, "Did we not prophecy in your name? Did we not preach a health message? Did we not look pious on Saturdays? The books - do they not testify to our righteousness?"

James, do you not believe that a Sunday law is being promoted and urged by many factions?

It doesn't matter because Jesus already stated how the world will be divided when He returns.

"When the Son of Man comes in His glory, and all the holy angels with Him, then He will sit on the throne of His glory. All the nations will be gathered before Him, and He will separate them one from another, as a shepherd divides his sheep from the goats." Matthew 25:31-46

And then He goes on to say that on the one hand would be those who reflected HIS LOVE but on the other, those who did not. Nowhere does He ever intimate, even remotely, about a National Sunday Law being a lightening rod for controversy to test who is for Him.

Indeed -- it is with the heart that we serve HIM, not just with outward show and pious words.
Indeed there will be those lost who will say, "but we kept the Sabbath"
"Wherefore the Lord said, Forasmuch as this people draw near me with their mouth, and with their lips do honour me, but have removed their heart far from me"

But those Who love Christ Jesus, will keep His commandments!

Also read the verses surrounding the one you quoted:
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.
7:22 Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
7:23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.

What was missing?
They were counting on their own works.
But they were not following the will of the Father.
They did not have a relationship with Christ, they did not know Him, thus He didn't know them.
They were engaged in iniquity (sin).

Activity does not save nor cleanse us. Only Christ can do that.
But notice that these people turned away, were turned away because they were engaged in sin, not following the will of the Father, and didn't have an intimate relationship with Christ.

But now, we see people take the texts that show that without the justification from Christ and without that relationship with Christ, all our "works" can never amount to any true righteousness, and they ignore the many texts that a true knowledge and surrendered relationship with Christ WILL cleanse and sanctify the believer, and will enable them to follow God's will and that this is an important and necessary part of living according to the will of God.

When we truly love God -- do we obey Him? Do we love His ways and commandments?

Or do we show our love for God, by disregarding His commands and doing our own thing in the way we want to do them?

You see -- when people "keep the Sabbath" simply as a cultural practice, yet are doing their own thing without much seeking after God -- then the Sabbath keeping means nothing.

But when people scoff at those who seek after God and His ways and laws, and discard God's commandment as if by disobeying it they are loving God -- they are definitely doing their own thing not obeying God's will.

And the foreigners who join themselves to the LORD, to minister to him, to love the name of the LORD, and to be his servants, all who keep the Sabbath...these I will bring to my holy mountain and make them joyful in my house of prayer...for my house shall be called a house of prayer for all peoples Isaiah 56:6-7

In Isaiah 56 the Sabbath stands out as a vital concern, affirming both its validity and universality.

Notice how it broadens the circle of people included:

56:2 Blessed is the man that does this, and the son of man that lays hold on it; that keeps the sabbath from polluting it, and keeps his hand from doing any evil.

Then the passage moves on to foreigners --

56:3 Don't let the son of a foreigner who joins God's people say, The LORD has utterly separated me from his people.
56:6 The foreigner..who loves the name of the LORD,...all who keep the Sabbath

Numerous historians have noted that Isaiah chapters 56-66 are filled with prophetic revelations of the future, not only of Christ's first coming, but more significantly of the time of the end.

Blessed, or "happy" is the person that does this...that keeps the Sabbath....
It is a privilege, a special connection of love with the LORD, bringing into sharp focus Who God is -- our Creator, and Redeemer.

The strangers, immigrants, all ethnic groups are called to the blessing of the Sabbath.
This passage clearly shows that the idea of the Sabbath being only for Jews is NOT God's idea.

The blessing is extended to all who "keep" "choose" "hold fast" --
all who " join themselves to the LORD, to serve him, and to love the name of the LORD, to be his servants, every one that keeps the sabbath from polluting it, and takes hold of my covenant;" ... " I will give them an everlasting name, that shall not be cut off."

And it doesn't say they won't be killing, won't be stealing, won't be worshiping idols....

In what way does He separate the sheep from the goats, what is the condition?
