21 For if God did not spare the natural branches, he will not spare you either. 22 Consider therefore the kindness and sternness of God: sternness to those who fell, but kindness to you, provided that you continue in his kindness. Otherwise, you also will be cut off. 23 And if they do not persist in unbelief, they will be grafted in, for God is able to graft them in again. 24 After all, if you were cut out of an olive tree that is wild by nature, and contrary to nature were grafted into a cultivated olive tree, how much more readily will these, the natural branches, be grafted into their own olive tree! 25 I do not want you to be ignorant of this mystery, brothers, so that you may not be conceited: Israel has experienced a hardening in part until the full number of the Gentiles has come in.

Those who reject the Messiah will taste the judgment from God for rejection. Those who embrace the Messiah will taste His kindness, His goodness, His salvation.

Paul says, ‘I don’t want you Gentiles to be ignorant of how God is planning to work with Israel.’ And the reason he makes this point is so that the Gentiles won’t be wise in their own eyes as to what God would do with the Jews.
It would be very easy to take their own understanding and conclude that Israel was completely out of the picture. But Paul says this mystery is that there is a partial hardening, which infers that it’s not total or final. And the Gentiles play a part in this mystery to the extent that when the fullness of the Gentiles is completed in God’s sovereign plan, the nation of Israel will be restored.
No one knows when this fullness will be completed. In fact, no one fully knows the mystery of what this fullness means. It could mean that when the last Gentile whom God foreknew comes into the Kingdom of God by faith in Christ then the Lord will begin His campaign to graft Israel back into the olive tree.
Others believe that the fullness of the Gentiles refers to God’s final plans with the Gentiles. However, as it relates to the fullness of the Gentiles, God is the One ultimately responsible with how He decides to work all things according to His will.
It is true that the plans of God are deep and complex amd we can not know them unless He reveals them to us.
I think this is a reference to the end times and to the remnant that I discussed earlier.
I am reminded again that salvation was for the Jew and that God in HIs mercy extended it to me and made me an adopted part of the Kingdom.
