Adventists along with others that hold the Sabbath is strictly binding will be fighting the battle of truth with the world's leadership and Sunday advocates. I rather believe the Jews will not have to comply perhaps as they are not Gentiles and Sabbath is binding only on them and not binding on them, the Gentiles. The Sunday Gentile world hold to John's statement "the LORD'S day" to be Sunday for them.
EGW has some powerful light on this for us,
The Remnant Make God Their Defense
"And at that time shall Michael stand up, the great Prince which standeth for the children of thy people: and there shall be a time of trouble, such as never was since there was a nation even to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book" [Daniel 12:1]. When this time of trouble comes, every case is decided; there is no longer probation, no longer mercy for the impenitent. The seal of the living God is upon His people. {LDE 259.2}
This small remnant, unable to defend themselves in the deadly conflict with the powers of earth that are marshaled by the dragon host, make God their defense.The decree has been passed by the highest earthly authority that they shall worship the beast and receive his mark under pain of persecution and death. May God help His people now, for what can they then do in such a fearful conflict without His assistance!--5T 212, 213 (1882). {LDE 259.3} God's People Flee the Cities; Many Imprisoned
As the decree issued by the various rulers of Christendom against commandment keepers shall withdraw the protection of government, and abandon them to those who desire their destruction, the people of God will flee from the cities and villages and associate together in companies, dwelling in the most desolate and solitary places. Many will find refuge in the strongholds of the mountains. . . . But many of all nations and of all classes, high and low, rich and poor, black and white, will be cast into the most unjust and cruel bondage. The beloved of God pass weary days bound in chains, shut in by prison bars, sentenced to be slain, some apparently left to die of starvation in dark and loathsome dungeons.--GC 626 (1911). {LDE 259.4}
Though a general decree has fixed the time when commandment keepers may be put to death, their enemies will in some cases anticipate the decree, and before the time specified, will endeavor to take their lives. But none can pass the mighty guardians stationed about every faithful soul. Some are assailed in their flight from the cities and villages; but the swords raised against them break and fall powerless as a straw. Others are defended by angels in the form of men of war.--GC 631 (1911). {LDE 260.1}
(Here is something to take serious note of, being at this time the Saints are very few and widely scattered people over this earth!)
The people of God are not at this time all in one place. They are in different companies and in all parts of the earth; and they will be tried singly, not in groups. Every one must stand the test for himself.--4BC 1143 (1908). {LDE 260.2}
The faith of individual members of the church will be tested as though there were not another person in the world.--7BC 983 (1890). {LDE 260.3}
Dear ones, there is no doubt each will be standing alone with what testimony each has and has stamina to put forth.
1Jo 4:4 ¶ Ye are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world. 1Jo 4:5 They are of the world: therefore speak they of the world, and the world heareth them. 1Jo 4:6 We are of God: he that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the spirit of truth, and the spirit of error. 1Jo 4:7 ¶ Beloved, let us love one another: for love is of God; and every one that loveth is born of God, and knoweth God. 1Jo 4:8 He that loveth not knoweth not God; for God is love.
