Is the second step, after rightly dividing the Bible, to then subtract all of those other Christians who didn't rightly divide it with you?
The name of the form of dispensationalism, like Ac2, Ac9, or Ac28, shows where the right division cut is cut and when they say the Gentile church started. All dispensationalism divides what pertains to Israel from what they think pertains to Gentiles, but they do it in different places.
It's not a matter of just cutting or dividing God's Word, it's a matter of dividing it rightly or correctly. We strongly believe that we're cutting it correctly and the other 2 types of dispensationalists are not cutting it correctly.
1- Acts 2 (Darby, Scofield, Larkin, etc.) thinks the Gentile Church started in Ac2. However, according to scripture, since no Gentile, except a proselyte, became a member of the Acts Church until 8 years after Ac2, and other reasons, I discount Ac 2 dispensationism as being false. Plus, everyone in the so-called Ac 2 Gentile church was an Israelite.
2- Ac 9 (Stam, O'Hair, etc) have the Gentile church starting in Ac 9, when Paul, THE apostle to the Gentiles, was saved on the Damascus Road. I discount Ac 9 for several reasons. One of the Ac 9 main tenants is that Israel was set aside, or whatever words they use, in Rom 11. If Israel wasn't set aside, it would be impossible to have a Gentile church. I discount Ac 9 for many different reasons. Here's a few.
----A- Israel's blindness in Ac 11 was only in "part", according to 11:25. It wasn't in "full" until Ac 28:26-27, when the full brunt of blindness from the curse of Isa 6:9_10 was imposed on them
----B- Later in Rom 11, we find that the Gentiles were let in to provoke Israel to Jealousy. Also, in Rom 11, we find that the saved Gentiles were grafted into the good Olive tree which was Israel. Back then, is was common to graft a wild olive branch into an old non-productive olive tree to make the old tree start producing again. Neither letting in Gentiles or grafting them into Israel make any sense if Israel was already set aside. The church throughout all of Acts is Jewish, because thevsaved Gentiles were grafted into and were, thus, part of Israel
---- C- In Ac 28, Paul was still preaching to the Jews first in Acts 28, a long time after Ac 20, aboutwhen Romans was written
3- Ac 28 dispensationalism (Welch, Oscar Baker,Allen, etc.) is the only one that covers all the bases. Although we absolutely believe a brand New church started in Ac 28:28, it doesn't come right out and say so. Here's a few of the reasons we believe the way we do.
----A- That powerful blinding, deaf curse of Isa 6 was definitely pronounced on Israel in Ac 28:26-27. Also, something was obviously transferred away from Israel and to the Gentiles in vs 28. It says the Salvation of God was passed. Most of us think this is Jesus Christ. The Messiah has dismissed Israel for the last 1950, or so, years
----B- The hope, calling, church, mystery, and everything else in Paul's last 7 books are totally different in most every respect than Paul's Acts books. The only thing I know of that was carried over from the Acts epistles to the post-Acts epistles was Paul's Gospel of Salvation of 1Cor 15:1-4, as is proven by several verses. Most importantly, there are many verses that prove those Gentiles in the after-Acts books have a calling of spending eternity in Heaven. No other people in the Bible have this calling. The calling of all the others is either the Earth or the New Jerusalem, which is not Heaven
----C- Unlike the churches selected by the other 2 types of dispensationalism, the after Acts church is all Gentile. In these books, it is obvious that Paul is only talking to Gentiles. Israel is almost totally absent, except to say thit, on this dispensation, Jews and Gentiles are equal. If a Jew wants to get saved, they have to believe Paul's Gospel in 1Cor 15:1-4, just like us Gentiles. Also, most all Jewish words are absent. "It is written" appears in Paul's Acts books 33 times. In his post-Acts books, it does not appear once.
I just re-read Eph and Col for the jillionth time, and it's amazing to me why people can't see the huge difference between Acts and after-Acts. To see after-Acts, I think you have to first remove your Acts spectacles and stomp on them. And mainly, stomp hard on the rature. Your "rapture" is the infinitely better "appearing", mentioned at least 5 times in Paul's after-Acts books, if you want. If you see it and believe it, it's yours if you accept the gift. If you accept it, whether it's true or not, it's a win-win proposition. If it's not true, you still have the rapture, which is not going away, no matter what you believe. You can't lose. What you believe now doesn't gain you anything beyond your salvation, which most all of us have. If what I am telling you is true, and I believe it is 100% true, it's the only thing other than salvation that takes faith to get. Get it before you get hit by a truck.
