Concerning your answer to the issue of Israel and the New Covenant. Biblically speaking the New Covenant was made with the House of Israel and Judah, collectively ISRAEL. Nowhere in the scriptures is it stated that the New Covenant was made with the Church (and I realize you never stated that it was). Israel as a whole did not reject Jesus, it was just their leadership. Multitudes of Jews, including priests at the time of Jesus believed in Him (Acts 6:7). Since those early days a remnant of Jewish people have existed that honor and acknowledge Jesus as their Messiah and live under the grace of the New Covenant. The New Covenant is with Israel but extends to all who wish to partake.
Whether they acknowledge it or not, everyone who accepts the New Covenant during the Church age is automatically part of the Church and will inherit the Church’s destiny, not Israel’s (Ephes. 1:11-14). In the Church there is neither Jew nor Gentile, slave nor free, male nor female, but all are one in Christ Jesus (Galatians 3:28). Everything else is just semantics.
