Israel and the church

Romans 11:2
God has not cast away His people which he foreknew.

Romans 11:11
Again I ask, did they stumble so as to fall beyond recovery? Not at all! Rather, because of their transgressions, salvation has come to the gentiles to make Israel envious.
But if their transgression means riches for the world, and riches for the gentiles, how much more greater will their fullness bring!

Deut. 32:21 speaking of an unfaithful Israel
They made me jealous by what is no god and angered me with their worthless idols. I will make them envious by those who are not my people.

God is jealous over his people Israel who have been unfaithful to Him. He plans at some future time to provoke Israel to envy with His love for another people. I sure hope that is us!

Romans 11:22-24
Therefore consider the goodness and severity of God: on those who fell, severity: but towards you, goodness, if you continue in His goodness. Otherwise you also will be cut off.
And they also, if they do not continue in unbelief, will be grafted in, for God is able to graft them in again.
After all, if you were cut out of an olive tree that was wild by nature (Gentiles), and grafted into a cultivated olive tree (Jews), how much more readily will these, the natural branches, be grafted into their own tree

Paul states that God is easily able to graft them back in. He uses pretty positive terminology (will be grafted into their own tree) I think God plans on doing just that.
This is combined with a stern warning to us - continue in His goodness, otherwise you will be cut off.
And a reminder of who we are and what our place is in the tree of faith. It seems to be pretty easy for us to start thinking a little too highly of ourselves.
I don't think this means that God loves any one or other of us more or less. I don't really know how God distributes His love, but I know that it is bigger than all of us. I think this is just a reminder of where we are in the political scheme of things, and we need to remember God has a plan. We need to stick to our part in it.

Romans 11:28,29
As far as the gospel is concerned, they are enemies on your account; but as far as election is concerned, they are loved on account of the patriarchs. For god's gifts and his call are irrevocable.

Did you hear that- irrevocable!

Romans 11:30
Just as you, who were one time disobedient to God, have now received mercy as a result of their disobedience,
so they too have now become disobedient in order that they too, may now receive mercy as a result of God's mercy to you.

There is a message here about the need for mercy, but that is a whole other topic.

So how might this work. We are to provoke them to jealousy by our relationship to God (Deut 32:21), whom they've always thought themselves to have a special relationship with. And their past disobedience has brought God's incredible mercy to us, now somehow God's mercy on us is to bring mercy to the Jewish people.

If the time of Jacobs troubles is nearly upon Israel, I believe now is the time for the church to pour out the love, mercy and compassion on Israel, that will provoke her by jealousy, Israel will see the great favor and close relationship her Christian brothers have with God, and in envy will open her eyes to see who her messiah is and pursue God.

Romans 11:25
For I do not desire, brethren, that you should be ignorant of this mystery (oh good, I love a 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 of 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.

So God has blinded Israel, and we carry the gospel for a time, in turn we are to show Israel God's love.

Besides, why would prophecy center around Israel if God had washed his hands of them?
