We are all God's chosen people, both Jew & Gentile, and as long as we accept His truth of the resurrection & follow His instructions very clearly laid out for us in the New Testament, then we shall have everlasting life. The answer to this lies in the new Covenant. In the New Testament which abolished the old of salvation through works, which I might add, does not mean that the laws of the Commandments were made null and void. Hardly. These are the laws of nature that all positive laws of man are to be founded upon.
John 14:6
Jesus said to him, I am the way, the truth, and the life. No one comes to the Father except through Me.
Where did salvation from works exist? It's always been by faith.
