Start with Yeshua’s clear words concerning WHO he came for:
Matthew 15:24
But he answered and said, I am not sent but unto the lost sheep of the house of Israel.
Then recognize that Paul went to established synagogues where these sheep were known to congregate, and where Paul himself had frequently gone to persecute those that had turned to The Way. He went now to re-graft the wild branches back to the natural root.
Acts 14:27 And when they were come, and had gathered the church together, they rehearsed all that God had done with them, and how he had opened the door of faith unto the Gentiles.
Acts 13:46 Both Paul and Barnabas replied courageously, “It was necessary to speak the word of God to you first. Since you reject it and do not consider yourselves worthy of eternal life, we are turning to the Gentiles. 47 For this is what the Lord has commanded us: ‘I have appointed you to be a light for the Gentiles, to bring salvation to the ends of the earth.”
But those who do Satan’s bidding answered just as we have seen here on this thread.
Acts 13:50 But the Jews incited the God-fearing women of high social standing and the prominent men of the city, stirred up persecution against Paul and Barnabas, and threw them out of their region.
Perhaps you might want to listen like Peter did to what he was told.
Acts 10:28 And he said unto them, Ye know how that it is an unlawful thing for a man that is a Jew to keep company, or come unto one of another nation; but God hath shewed me that I should not call any man common or unclean.
NAh; let's start with YOURS!
Don’t forget that those “gentiles” happen to be mostly out of covenant members of the “House of Israel” in dispersion.
