This reminds me of the typical "water baptism required for salvation or not" debate.
It seems many of us are clear that water baptism is not required for salvation, until we can confidently say, even if a person believes in Jesus's DBR but choose not to get water baptized, he will still be saved.
That is how we can believe salvation is by faith alone apart from works.
But when it comes to Tribulation and the mark of the beast, we are confined by Rev 14 that clearly states that anyone who does not reject the mark will be thrown into the lake of fire.
Yet, some still want to hold on to this "salvation is ALWAYS by grace thru faith alone", thus they find ourselves resorting to circular arguments like "If you are truly saved, you will always reject the mark of the beast, but it is still salvation by faith alone".
Imagine if we do that for water baptism, "Water baptism does not save you, but if you are saved, you will always get water baptized, but water baptism still does not save you", and the circularity goes on and on.
LOL,Guojing. You really don't need anybody to debate with. You just put words in people's mouths and then debate with yourself. Cracks me up.
Returning to the tribulation scenario ... it might help if I clarify something that is missing here.
Say that somehow Bob, the one who thinks he's saved, but it was only words to him without a saving faith, manages to survive the tribulation without taking the mark, and without being killed. Will he go into the Millennial Kingdom along with all of the righteous saved who managed to survive the tribulation?
No. His false conversion condemns him just as much as if he had taken the mark. It's like all of the supposed "Christians" sitting in pews today who will be very surprised to find themselves left behind at the rapture.
He will be a "goat" in the sheep and goats judgment and will be cast into the lake of fire along with the other goats.
See what I mean. The mark as a "test" of works is totally irrelevant to whether someone is saved or not.
Let me use your scenario then. Suppose Bob in year 1 really believed that Jesus died for his sins, and rose again for justification.
He asked John, "Am I really saved? I put my faith in the DBR of Jesus. Is salvation really based on faith alone apart from works?"
John will naturally reply, "Yes, you put your faith in Jesus DBR, you are saved!" He did not tell him anything about rejecting the mark because, after all, its by faith alone. That is what the Apostle Paul stated in his letters.
Year 6 comes, the 2nd half of the Tribulation. Bob told John "I had to register my kid to school because kids need education, but they say I cannot use cash, I have to use the mark of my head, in order to pay for the kid's tuition in school. So I took the mark."
John would say, "Ooooh too bad, now that you took the mark, you are no longer saved, it shows you don't really believe in Jesus years ago".
Bob would reply, "But you told me earlier that salvation is by faith alone, how come you never tell me about this additional condition? You liarrrrrrrrrrrrr!"
In your scenario, even the Devil believes Jesus was real and knows that he died and rose again. John was wrong to tell Bob he was saved merely by believing some words.
You said:
"I had to register my kid to school because kids need education, but they say I cannot use cash, I have to use the mark of my head, in order to pay for the kid's tuition in school. So I took the mark."
And that exactly proves my point. It doesn't exactly sound like the Holy Spirit talking in Bob, does it. How could someone who is truly saved give up eternity in heaven with the Lord for the trifling benefit of putting his kids in school. The martyrs suffered much, much, much worse without renouncing their faith.
Once again you refuse to acknowledge that I am saying that Bob didn't lose salvation
because of taking the mark. He just never had salvation in the first place. It's true that salvation is by faith alone. But that faith has to be real, right? Not just words without true faith.
I have to admit I'm looking forward to seeing your next contribution to putting words in my mouth and then arguing with yourself.
