Romans 9:16-33

It does not, therefore, depend on man's desire or effort, but on God's mercy. For the Scripture says to Pharaoh: "I raised you up for this very purpose, that I might display my power in you and that my name might be proclaimed in all the earth."Therefore God has mercy on whom he wants to have mercy, and he hardens whom he wants to harden. One of you will say to me: "Then why does God still blame us? For who resists his will?" But who are you, O man, to talk back to God? "Shall what is formed say to him who formed it, 'Why did you make me like this?' "Does not the potter have the right to make out of the same lump of clay some pottery for noble purposes and some for common use? What if God, choosing to show his wrath and make his power known, bore with great patience the objects of his wrath—prepared for destruction? What if he did this to make the riches of his glory known to the objects of his mercy, whom he prepared in advance for glory— even us, whom he also called, not only from the Jews but also from the Gentiles? As he says in Hosea: "I will call them 'my people' who are not my people; and I will call her 'my loved one' who is not my loved one,"and, "It will happen that in the very place where it was said to them, 'You are not my people,' they will be called 'sons of the living God.' "

Isaiah cries out concerning Israel: "Though the number of the Israelites be like the sand by the sea, only the remnant will be saved. For the Lord will carry out his sentence on earth with speed and finality." It is just as Isaiah said previously: "Unless the Lord Almighty had left us descendants, we would have become like Sodom, we would have been like Gomorrah."

What then shall we say? That the Gentiles, who did not pursue righteousness, have obtained it, a righteousness that is by faith; but Israel, who pursued a law of righteousness, has not attained it. Why not? Because they pursued it not by faith but as if it were by works. They stumbled over the "stumbling stone." As it is written:

See, I lay in Zion a stone that causes men to stumble and a rock that makes them fall, and the one who trusts in him will never be put to shame."

I Peter 2:4-9

As you come to him, the living Stone—rejected by men but chosen by God and precious to him— you also, like living stones, are being built into a spiritual house to be a holy priesthood, offering spiritual sacrifices acceptable to God through Jesus Christ. For in Scripture it says: "See, I lay a stone in Zion, a chosen and precious cornerstone, and the one who trusts in him will never be put to shame."
Now to you who believe, this stone is precious. But to those who do not believe, "The stone the builders rejected has become the capstone and, "A stone that causes men to stumble and a rock that makes them fall."

They stumble because they disobey the message—which is also what they were destined for.

But you are a chosen people, a royal priesthood, a holy nation, a people belonging to God, that you may declare the praises of him who called you out of darkness into his wonderful light.
