Babylon is forming in the world right now before your very eyes, is as religious as you could possibly imagine, and you can't see it. Explains why the whole world, including every denomination and nation, and yes, even some in my own, will be deceived by her lies and receive the beast's mark.
In order to understand, you would do better to start at the beginning, slowly, with no unbiblical assumptions and presumptions, and rely on God's word, for the Bible explains and interprets itself.
I have good reason to offer the above advice... Your eschatology is as confusing as Babylon itself. Like others here, you are using disparate verses from here and there and made to force fit a preconceived theory. You mock, as others do, SDA eschatology, yet you fail to grasp the very first principles we teach. Your objections to our teachings are as empty as the Jesuit futurist theories you propagate.
LOL, what?
Those words suddenly mean nothing considering the fact that you believe the mark of the beast is Sunday worship which everyone knows isn't something from the bible at all!
Take your own advice and focus on real possibilities for what the mark will be.
It's curious that you are so confident about your understanding of what the
mark of the beast is, yet do not know
who the beast is. That's why you need to start at the beginning.
You don't even have that correct about "Sunday worship". There are several factors involved, not the very least of which is the trampling of the Sabbath, the real 4th commandment, and not the counterfeit. Another factor is state legislation on behalf of Sunday 'sacredness' at the behest of the church. Hence why there is no mark of the beast
yet. If you cannot see the realities of those factors being played out in real life throughout the world of politics and religion right now, you are are looking in all the wrong places to see the signs of the times.
Revelation reveals a contrast between those who receive the mark, and those who receive the seal of God. Both are in the forehead, and one can be received in the hand. One cannot have one in the forehead and leave room for the other. In the forehead is the conscience. Whatever the mark is, it is in opposition to the seal of God, which is a spiritual concept accepted and received by faith. It is conscientiously believed and impacts the life, both spiritually and physically. Read about the 144000, not a literal number, and not literal Jews, but an unknown vast eklessia and are otherwise known as spiritual Israel, in contrast to spiritual Babylon.
Another contrast is that those who receive the seal of God also keep the commandments of God and have the faith of Jesus. Those in Babylon don't. They reject the law of God and have their own laws, keeping and teaching the commandments of man as doctrine. Those false doctrines are in the woman's cup, and are what makes the world drunk. They become blind and oblivious to spiritual realities and readily deceived because they have no love for the truth.
PS. A. The scripture says nothing about those who keep the Commandments of God as observing only 9 of them.
B. All laws contain or have added to them the seal of the Lawmaker. Most seals have 3 components to them... The name of the Lawmaker... The title that belongs to him... And the kingdom he presides over. Now remove the 4th commandment from the tables of stone, and show us from what remains who the lawgiver is. Where is the seal?
If you've followed me this far, then you may draw some conclusions, but as I said, first you need to discover who the first beast of Revelation 13 is, and realize it is the second beast who enforces the mark. So you also need to discover who that beast represents.
Stop relying on Jesuit teachings which hide the identity of the Antichrist. The world has been captivated and deceived by them through futurism. Do some research and find out
why the reformers were all on the same page when it came to identifying Antichrist... It is the one thing they actually agreed on.
