Has God rejected the Jews? The apostate Israelites of Elijah's day didn't stop being Israel because they were apostate. God always preserves a remnant of the natural descendants of Jacob and, through them, the whole nation. Nor can he reject his covenant with them. So long as God himself lives and a single descendant of Jacob lives, God cannot annul the covenant that made Israel his people.
