Jeremiah 31.33-34 seems to have a different idea on how God will be treating Israel. I'm not sure I can agree with a 'setting aside' mentality. It isn't supported biblically.
It isn't supported biblically?? Almost the entire New Testament is devoted to the topic.
And as far as Jeremiah is concerned it holds one of the biggest keys of all...
Jer 18:5 Then the word of the Lord came to me, saying: 6 “O house of Israel, can I not do with you as this potter?” says the Lord. “Look, as the clay is in the potter's hand, so are you in My hand, O house of Israel! 7 The instant I speak concerning a nation and concerning a kingdom, to pluck up, to pull down, and to destroy it, 8
if that nation against whom I have spoken turns from its evil, I will relent of the disaster that I thought to bring upon it. 9 And the instant I speak concerning a nation and concerning a kingdom, to build and to plant it, 10
if it does evil in My sight so that it does not obey My voice, then I will relent concerning the good with which I said I would benefit it.
Israel's continual disobedience caused God to set them aside. It's not permanent however. God will return to them when He is done dealing with the gentiles.
Romans 11:11 I say then, have they stumbled that they should fall? Certainly not!
But through their fall, to provoke them to jealousy, salvation has come to the Gentiles. 12 Now if their fall is riches for the world, and their failure riches for the Gentiles, how much more their fullness!
13 For I speak to you Gentiles; inasmuch as I am an apostle to the Gentiles, I magnify my ministry, 14 if by any means I may provoke to jealousy those who are my flesh and save some of them. 15 For if their being cast away is the reconciling of the world, what will their acceptance be but life from the dead?
16 For if the firstfruit is holy, the lump is also holy; and if the root is holy, so are the branches. 17 And if some of the branches were broken off, and you, being a wild olive tree, were grafted in among them, and with them became a partaker of the root and fatness of the olive tree, 18 do not boast against the branches. But if you do boast, remember that you do not support the root, but the root supports you.
19 You will say then, “Branches were broken off that I might be grafted in.” 20 Well said.
Because of unbelief they were broken off, and you stand by faith. Do not be haughty, but fear. 21 For if God did not spare the natural branches, He may not spare you either. 22 Therefore consider the goodness and severity of God: on those who fell, severity; but toward you, goodness, if you continue in His goodness. Otherwise you also will be cut off. 23 And they also, if they do not continue in unbelief, will be grafted in, for God is able to graft them in again. 24 For if you were cut out of the olive tree which is wild by nature, and were grafted contrary to nature into a cultivated olive tree, how much more will these, who are natural branches, be grafted into their own olive tree?
25 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. 26 And so all Israel will be saved, as it is written
