Most Dispensationalists couldn't care less whether or not a segment of the Church believes it will go through the Tribulation. I am among that group.
This is one line that gave me pause. Does it matter from scripture when the rapture happens?
I do realize the main thesis of the essay the dispensational label vs covenant label. BTW Why do we need labels that put us in groups?
Well, a person's belief in the timing doesn't affect his salvation, however, the outright denial of the God-give doctrine of the Rapture is a huge problem. And, the denial of the Scripture that tells us the Church will not be here for the Tribulation is a huge problem. If you have to deny Scripture for your belief to work, then your belief is a false doctrine.
No true Christian will deny any part of Scripture.
As has been demonstrated repeatedly on this forum, God assures us that He will take His bride off the scene before He sends judgment. And, since He tells us to "comfort one another" with those assurances, we can rest easy knowing that we are not destined for the judgment God has for those who have chosen to reject Him and who love evil and love to practice evil.
BTW Why do we need labels that put us in groups?
The way one reads and interprets Scripture is extremely important and can affect a person's eternal destiny. If someone believes that the Scripture is not entirely true, or is fallible, or has errors, that is going to influence his worldview, and how he lives his life. If a person believes that the Scripture should not be taken as God gave it to us, but that men have the omniscience and the authority to allegorize the Bible, which makes it meaningless and open to any view that any person may have, this can also affect a person's eternal destiny. After all, if the Bible has errors, or is open to being allegorized, how do we know that Jesus Christ really died to rescue mankind? Who is to say?
Unfortunately, "labels" are sometimes necessary because labels enable people to distinguish between belief systems. If, for example, someone takes it upon himself to allegorize the book of Revelation, which, again, takes what God intended for man to have as a warning and as a gift to know how this age is going to end, and we see, in our generation, the technology necessary for the literal fulfillment of Revelation 13:16 ready to be implemented, then those who have bought into the idea that the book of Revelation is nothing but a fairy tale, a book of meaningless symbols, are not going to recognize this stage-setting for what it is. A dispensationalist will tell people that that verse is a literal, future prophecy that is in the process of being fulfilled in our generation. A person who allegorizes that passage will tell you not what God tell us, but what he thinks it means. And, you will get a different interpretation from each person who believes that that Scripture should not be taken literally, but as some kind of symbol that really doesn't mean anything.
So it is very important to have labels so that people can differentiate between truth and error; between deception and trustworthiness.
