It really funny how fixated you are on Paul preaching Christ in a synagogue to the "Men of Israel, and ye that fear God" and " Men [and] brethren, children of the stock of Abraham, and whosoever among you feareth God" (Act 13:16 & 26).
This entire passage simply shows Israel's continued rejection of their Messiah, which is the primary purpose of the book of Acts.
I'm very curious to understand THIS verse in light of the alleged removal of all "ethnic distinctions" at that precise time of the cross as you and many other claim.
Acts 13:46 (AKJV/PCE)
(13:46) Then Paul and Barnabas waxed bold, and said, It was necessary that the word of God should first have been spoken to you: but seeing ye put it from you, and judge yourselves unworthy of everlasting life, lo, we turn to the Gentiles.
WHY was it "necessary that the word of God should first have been spoken to you"?
Your other compulsive disorder of the book TO THE HEBREWS is also fascinating. Everything in Hebrews and Revelation is completely and totally SATURATED with Israel
Heb 12:25-29 (AKJV/PCE)
(12:25) See that ye refuse not him that speaketh. For if they escaped not who refused him that spake on earth, much more [shall not] we [escape], if we turn away from him that [speaketh] from heaven: (12:26) Whose voice then shook the earth: but now he hath promised, saying, Yet once more I shake not the earth only, but also heaven. (12:27) And this [word], Yet once more, signifieth the removing of those things that are shaken, as of things that are made, that those things which cannot be shaken may remain. (12:28) Wherefore we receiving a kingdom which cannot be moved, let us have grace, whereby we may serve God acceptably with reverence and godly fear: (12:29) For our God [is] a consuming fire.
The WE throughout HEBREWS is the HEBREWS. The WE receiving the kingdom is the HEBREWS (i.e., Israel).
When does Paul call OUR God a "consuming fire"? God is NOT spoken of this way in THIS dispensation of God's GRACE!
