There are those who teach that by rejecting Jesus Christ, the Jews voided their right to be called Jews. By that reasoning, those who rejected Jesus Christ have lost all distinction in the eyes of God. Not so; speaking of the Jews, the Apostle Paul had this to say: As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the fathers' sakes, Romans 11:28.
That passage is enlightening for many reasons. It clearly identifies Jews who disagree with Christians about the Gospel. It calls them enemies. At the time the apostle Paul wrote that, the shoe was on the other foot. It was Jews who were tracking down Christians. Is Paul calling for war against them? Hardly, he tells us that because of their fathers, God calls them beloved. God cannot look at a Jew today without remembering his promises to Abraham, Isaac and Jacob.
I have family today (please don't hold this against me) who vote for Democrats. Within the context of elections we are enemies. Never, would any of us ever think of persecuting the other. I have other family (I know I'm pushing the tolerance level) who are New York Yankees fans. Obviously, being a lover of good and upright baseball, in the context of baseball, they are my enemies. We don't hate each other. These are contextual enmities.
Likewise, with the Jew. Under the umbrella of all who hold the Old Testament as sacred, we disagree. There is a curse to those who would curse a Jew. And I will bless them that bless thee, and curse him that curseth thee: and in thee shall all families of the earth be blessed, Genesis 12:3. Every Bible believing Christian needs to keep that in context. The other astounding thing about Romans 11:28, is that Paul calls Jews who have rejected the Gospel, "elect". As touching the election, they are beloved for the fathers' sake. They are still the chosen people of God.
