The Church is Not Israel
I say then, has God cast away His people? Certainly not!
For I do not desire, brethren, that you should be ignorant of this mystery, lest you should be wise in your own opinion, that blindness in part has happened to Israel until the fullness of the Gentiles has come in. And so all Israel will be saved, as it is written: "THE DELIVERER WILL COME OUT OF ZION, AND HE WILL TURN AWAY UNGODLINESS FROM JACOB; FOR THIS IS MY COVENANT WITH THEM, WHEN I TAKE AWAY THEIR SINS."
