Well they do have an agenda, it is to glorify God. These bible thumping fundie Christians, that loopy faith, just have this crazy idea, ya know, that the Jewish line is permanently marked with God's favor, even though they don't deserve it. Kind of like what these Jewish guys' prophets were telling them back in the (good/bad) old days... like the bible is actually true, what an odd notion! Christian humility comes (or should come) from the realization that they themselves too, did not deserve the favor that came to them from God.

What do you mean by "Jewish line?" Biological descendancy from Abraham doesn't count. "[D]o not suppose that you can say to yourselves, 'We have Abraham for a father,' for I say to you that God is able from these stones to raise up children to Abraham."
Do you think that those who call themselves Jews today are the inheritors of the covenant promise?
