Thanks for taking the time to type all this and I appreciate you working with me. I feel the same about seeing something clearly that others can’t see. I’m going to digest this and get back with you, but here is one thing that jumped out at me.
I get the feeling you didn't even look at Paul's sermon in Acts 13.
You said.
Paul's message is the same as Peter's.
16 Paul stood up, and motioning with his hand said, "Men of Israel, and you who fear God, listen:
23 From the descendants of this man, according to promise, God has brought to Israel a Savior, Jesus,
This, I think, illustrates a major mistake most Christians make. Not just on dispensational issues but on every issue. They take individual passages and apply them as though they exist in a vacuum. The book of Acts is a historical account of the transition from one dispensation to another. In fact, the very existence of the book of Acts is an argument in favor of the idea that the dispensation changed at some point after Calvary because otherwise there would be no need for the book of Acts to begin with, at least not a doctrinal need for it. But Acts 13 was not written by itself. It is just a continuation of the story line and CANNOT be removed from that context without confusion.
As I've been reading and trying to figure out how to respond to this objection I keep coming around to the notion that I'd have to basically write a commentary of most of the book of Acts to really cover all the bases here but time just will not allow for such a thing and so I'm going to give you an answer that I really sort of hate to give you because it will be woefully incomplete and is likely to only create more questions than it answers and may perhaps be counterproductive to convincing you of anything. My hope is to convince you to at least look into the subject with more detail than is possible on a web forum.
So, here goes nothin'...
Once again, while I'm not going type it all out verbatim this time, I am, once again, leaning heavily on Bob Enyart's The Plot, a book I beg you to read for yourself...
In Acts 10 & 11 God informed the Twelve that the Gentiles were no longer "unclean" and were acceptable without the need to become proselyte Jews (i.e. be circumcised etc.). Next, in Acts 12 you have a 2nd murder of a follower of Christ which sort of bookends God's turning to the Gentiles. You have the murder of Stephen in Acts 8 by the religious leaders of Israel and then the murder of James in Acts 12 by the political leader of Israel. Then in Acts 13 & 14 God makes it clear to the nation itself, the people of Israel, that He has turned to the Gentiles.
Right off the bat Paul and Barnabas are separated for their ministry to the Gentiles (Acts 13:2)
Paul preached, at first, to both Gentiles (Acts 13:12) and to the Jews but the Jews simply rejected Paul's message which was quite different than anything that had come before.
[Paul] went into the synagogue on the Sabbath day...and said, "Men of Israel, and you who fear God, Listen:... From [King Davids] seed, according to the promise, God raised up for Israel a Savior----Jesus... sons of the family of Abraham, and those among you who fear God, to you the word of this salvation has been sent... (Acts 13:14, 16, 23, 26)
All of which sounds fine but then Paul drops the following bomb on them...
and by [Jesus] everyone who believes is justified from all things from which you could not be justified by the law of Moses. Acts 13:39
This truth cannot be found in the law of Moses itself, nor any of the Old Testament, nor the Gospels and not even in the book of Acts until Paul begins his ministry. And the Jews opposed the things preached by Paul and so Paul and Barnabas sort of got in the Jew's face and said fine! If you judge yourselves unworthy of everlasting life, we'll go to the Gentiles. (Acts 13:43 & 45)
In chapter 14 Paul preaches to everyone without distinction and many believed (Acts 14:1). Some even thought they were Zeus and Hermes! And you should note that there is no record of the Twelve having to deal with this sort of thing since they never went to the Gentiles but ministered only to the believers in/of Israel.
And finally, at the end of chapter 14 Paul emphasizes that God had turned to the Gentiles...
Now when they had come and gathered the church together, they reported all that God had done with them, and that He had opened the door of faith to the Gentiles.
Notice, "God had opened the door of faith to the Gentiles."!
The "door of faith" had been shut to all nations accept Israel prior to God turning to the Gentiles in Acts 9. Basically speaking, starting from Abraham, when he received the Covenant of Circumcision up until the conversion of Paul on the Damascus Road, salvation went to the Jews or to proselytes (i.e. you either had to be a Jew or become one). Everything prior to Acts 9 was about the Jews and the nation of Israel.
Going back to the gospels through Acts 2...
The death of Christ (Feast of Passover)
Christ in the grave (Feast of Unleavened Bread)
Christ's Resurrection (Feast of First Fruits)
The giving of the Holy Spirit (Feast of Weeks or Pentecost)
All of these feast occurred ON THE ACTUAL DAY OF THE FEAST, precisely on time in direct fulfillment of prophecy. The next would have been the Feast of Trumpets and then the Day of Atonement followed by the Feast of Tabernacles. None of which were fulfilled as expected (some believe that Tabernacles was fulfilled with Christ's birth based on the wording of John 1:14). The question is why?
Acts 8 - 14 is why. With the stoning of Stephen, God began the process of casting away Israel and turning instead to the Gentiles.
Resting in Him,
