The church during Acts was a body of believers whose leader was Christ. It was 100% Israel, since all the Gentiles in the church were grafted into Israel and were, therefore, part of Israel. The ONLY purpose of grafting a few Gentiles into the all-Israel Acts church that started at Pentecost and ended at the end of Acts, was to provoke the nation Israel to jealousy, so they might believe in Christ, so Christ would return and Israel's earthly Kingdom of Heaven would be set up. The Gentiles in Acts were given a few of the same blessings that the Jewish members had - the gifts, the rapture, the calling of the New Jerusalem. The Gentiles in the church did not have the covenants or the law, the adoption (which means they had no inheritance), none of the promises of God made to Abraham, Issac, Jacob, and David, and, they couldn't preach or teach, since Israel had the Service of God. See Rom 9:4. Is that what you want?
Nothing ever given to Israel was also given to the Gentiles, unless it says so in scripture, like the gifts, rapture, and the calling of the NJ were. However, those all faded out at the end of Acts, when Israel, as a nation, was set aside, and their hope of Israel's earthly Kingdom of Heaven was postponed for at least 2000 years. The stealing of Israel's blessings is the denominational system's stock in trade. If you removed all the doctrine stolen from Israel, which definitely has NOTHING to do with Gentiles today, they would have nothing to talk about. NONE see the truth of the new church in Paul's 7 after-Acts epistles. Only in those 7 books will you find the marching orders for the Gentile church today. Only there will you find that your calling is not the New Jerusalem, as was the calling in ALL of Acts, but is now the calling of actual Heaven. If the calling is different, EVERYTHING is different.
No one that can read could ever say that the book of James is written TO Gentiles today. For those that believe their Bible, they will believe James 1:1, which says it was written to the 12 tribes of Israel. If you're not a descendant of Jacob and if you don't practice the full law, James is NOT written TO you - DUH! People have forgotten how to read. Almost everything taught in Christendom today has zero basis in Bible truth. It's ALL what people wish it was and not what it really is.
Why anyone would want those meagerly things the Gentiles in Acts were given, when everything after-Acts is infinitely better, is beyond my comprehension. You can't have both. Also, those who believe that they can now claim those things not given to Gentiles, at the time they were given to Israel, are living in a dream world. If you didn't get it then, where does it say you can have it now? If it doesn't say that it's for Gentiles today, it isn't for Gentiles today.
All of this idiocy started with the 100% false, un-scriptural idea that Israel was finished, due to their unbelief, and were replaced by the "Church". That phony concept is being taught by more preachers than most people think. My guess is that Israel will be back on the scene in about 2063, or 2000 years after they were set aside at the end of Acts, in about 63AD.
The biggest difference in you and I is that I believe the only blessings in scripture to Gentiles are those specifically given to Gentiles, and you believe that you rightly deserve all the blessings in scripture given only to Israel. You don't realize it, but you're all replacement theoligists. Of course, as with all replacement theologists, this means that you'll never get what you think you'll get. And, I can't see God giving you what you should get in Eph, Col, etc., if you don't believe in it. That's why He approves those who divide His word rightly, thus weeding out all the myriads of Israel-only things from your faulty doctrine. I don't blame you for this, since you are a product of 2 millenniums of faulty Christianity. The origin of this was that Paul, the ONLY apostle you have and the VERY LAST WORD in your actual true doctrine, was essentially dismissed until the last 200 years, or so.
I apologize for my constant badgering on these points. However, I truly believe that, if you don't get rid of all that Jewish baggage from Acts, that you all carry around, God won't give you, Eph 1:17-18, "the spirit of wisdom and revelation in the knowledge of him: The eyes of your understanding being enlightened; that ye may know what is the hope of his calling, and what the riches of the glory of his inheritance in the saints" Why would Paul pray for this, if Heaven were automatic for all believers.
The only place you find the "hope of your calling", which is Heaven, itself, is in Paul's 7 after-Acts books. According to Paul's prayer, above, God has to give you the eyes of understanding to SEE this hope of Heaven. No one in Acts or any of those in the other 59 books ever had a hope of Heaven, so, if you believe all those INFERIOR things in Acts belong to you, why would God give you those SUPERIOR things found ONLY in Eph, Phil, Col, 1&2Tim, Titus, and Philemon. Be approved unto God (2Tim 2:15) by making a single straight cut (rightly dividing) through God's Word of Truth at the only possible place to divide Israel from the Gentiles - Acts 28:28. Then, for things that apply TO you, eliminate everything that you believe from the Israel side of the cut, and believe only those things on the Gentile side of the cut.
