No! No! No! and a thousand times No! God has not terminated His relationship with His ancient people Israel. This fact cannot be overstated, especially in these days when so-called "Replacement Theology" is gaining popularity; asserting that the church has taken the place of Israel in God's plan and purposes.
The question posed above, however, is not a new one, nor is it merely a reaction to the falsehood stated. The same question obviously existed in peoples minds in the New Testament days. The great apostle Paul, the theologian of the New Testament, poses this question rhetorically in his treatise on Israel in Romans 9-11. He says, "Hath God cast away his people? God forbid. For I am an Israelite, of the seed of Abraham, of the tribe of Benjamin. God hath not cast away his people which He foreknew" (Romans 11 :1-2a).
