God has not cast off all Israel.

11:1 I ask then, did God reject his people? May it never be! For I also am an Israelite, a descendant of Abraham, of the tribe of Benjamin.

11:2 God didn’t reject his people, which he foreknew. Or don’t you know what the Scripture says about Elijah? How he pleads with God against Israel:

11:3 “Lord, they have killed your prophets, they have broken down your altars; and I am left alone, and they seek my life.”*

1 Thessalonians 2:15

11:4 But how does God answer him? “I have reserved for myself seven thousand men, who have not bowed the knee to Baal.” *

1 Kings 19:18

11:5 Even so then at this present time also there is a remnant according to the election of grace.

Genesis 45:7

11:6 And if by grace, then it is no longer of works; otherwise grace is no longer grace. But if it is of works, it is no longer grace; otherwise work is no longer work.

Some were elected, though the rest were hardened.

11:7 What then? That which Israel seeks for, that he didn’t obtain, but the chosen ones obtained it, and the rest were hardened.

Matthew 24:22

11:8 According as it is written, “God gave them a spirit of stupor, eyes that they should not see, and ears that they should not hear, to this very day.”*

11:9 David says,
“Let their table be made a snare, and a trap,
a stumbling block, and a retribution to them.

11:10 Let their eyes be darkened, that they may not see.
Bow down their back always.”*

11:11 I ask then, did they stumble that they might fall? May it never be! But by their fall salvation has come to the Gentiles, to provoke them to jealousy.

James 2:10

11:12 Now if their fall is the riches of the world, and their loss the riches of the Gentiles; how much more their fullness?

11:13 For I speak to you who are Gentiles. Since then as I am an apostle to Gentiles, I glorify my ministry;

1 Corinthians 1:1

11:14 if by any means I may provoke to jealousy those who are my flesh, and may save some of them.

11:15 For if the rejection of them is the reconciling of the world, what would their acceptance be, but life from the dead?

There is hope of their conversion.

11:16 If the first fruit is holy, so is the lump. If the root is holy, so are the branches.

11:17 But if some of the branches were broken off, and you, being a wild olive, were grafted in among them, and became partaker with them of the root and of the richness of the olive tree;

The Gentiles may not exult over them;

11:18 don’t boast over the branches. But if you boast, it is not you who support the root, but the root supports you.

11:19 You will say then, “Branches were broken off, that I might be grafted in.”

11:20 True; by their unbelief they were broken off, and you stand by your faith. Don’t be conceited, but fear;

Romans 12:3

11:21 for if God didn’t spare the natural branches, neither will he spare you.

11:22 See then the goodness and severity of God. Toward those who fell, severity; but toward you, goodness, if you continue in his goodness; otherwise you also will be cut off.

11:23 They also, if they don’t continue in their unbelief, will be grafted in, for God is able to graft them in again.

Jeremiah 3:12

11:24 For if you were cut out of that which is by nature a wild olive tree, and were grafted contrary to nature into a good olive tree, how much more will these, which are the natural branches, be grafted into their own olive tree?

11:25 For I don’t desire you to be ignorant, brothers, of this mystery, so that you won’t be wise in your own conceits, that a partial hardening has happened to Israel, until the fullness of the Gentiles has come in,

for there is a promise of their salvation.

11:26 and so all Israel will be saved. Even as it is written,
“There will come out of Zion the Deliverer,
and he will turn away ungodliness from Jacob.

Isaiah 59:20

11:27 This is my covenant to them,
when I will take away their sins.”*

Acts 3:26

11:28 Concerning the Good News, they are enemies for your sake. But concerning the election, they are beloved for the fathers’ sake.

2 Peter 1:10

11:29 For the gifts and the calling of God are irrevocable.

11:30 For as you in time past were disobedient to God, but now have obtained mercy by their disobedience,

11:31 even so these also have now been disobedient, that by the mercy shown to you they may also obtain mercy.

11:32 For God has shut up all to disobedience, that he might have mercy on all.

God's judgments are unsearchable.

11:33 Oh the depth of the riches both of the wisdom and the knowledge of God! How unsearchable are his judgments, and his ways past tracing out!

11:34 “For who has known the mind of the Lord?
Or who has been his counselor?”*

Isaiah 40:14

11:35 “Or who has first given to him,
and it will be repaid to him again?”*

11:36 For of him, and through him, and to him, are all things. To him be the glory for ever! Amen.
