The fact that Jesus spoke to the Jews is due to His having come to save His own people FIRST, then He sent His disciples to preach the same message to the Gentiles.
Context does not separate His gospel from the Jews or the Gentiles it united them in the faith of Abraham.
Many here get uncomfortable, some even get a bit riled up, when they hear the word, Jew, for many equate the Children of Israel with Jews, and they are right, at least 1/12th right.
The Gospel for the Children of Israel is for them all, even those joined to them, so do not say one thing is true for Israel and another for Gentiles or yo uare saying you are still Gentile, Pagan.
Again, the majority here think acknowledging the Israel of God as being the Children of Israel with the Gentiles converted graffed in is wrong, and not of God, but I am afraid you are not hearing the Godd Shepherd Who has unified that other flock, Gentiles, with His original flock, Israel. Or do you believe the words in Ephesians teaching us that we are become God's nation with Israel are in error? If this is the case, you should write your own Bible, but it will not be in the Hoy Spirit if you teach agains these teachings.
You grace only to the nth power folsk will not understand this at all.
