It appears to me that those two things are mutually exclusive, AA.
The gospel of the kingdom said: "Repent for the kingdom is at hand." Good news for an Israelite who awaited the national promise. In the promised kingdom, they would be under a new covenant where (like the Body of Christ) there would be eternal righteousness, sins would be blotted out forever, etc. But they would receive those promises AFTER they inherited their earthly promises.
The promises to the Body are spiritual promises that we receive immediately upon belief. We are baptized into the body, where we receive immediate forgiveness of sins, are immediately reckoned as righteous, etc. And we are seated in the heavenlies with Christ (who is our life).
So a member of the body (who got there by believing the gospel of Christ) is immediately saved and awaits a heavenly abode. A member of the circumcision was to faithfully endure to the very end, after which he would receive salvation, permanent forgiveness of sins (he could be forgiven before then, but not permanently), eternal righteousness, etc. He awaited an earthly abode (descriptions make it seem just like I imagine Eden was).
Based on that, I don't see how an "uncircumcision believer" (member of the Body) could receive the promises to the "circumsion believer".
I have more thoughts on that, but it would only confuse the issue now, so I'll leave it at that.
