God still has a plan for Israel

^25-27 Now I don’t want you, my brothers, to start imagining things, and I must therefore share with you my knowledge of God’s secret plan. It is this, that the partial insensibility which has come to Israel is only to last until the full number of the Gentiles has been called in. Once this has happened, all Israel will be saved, as the scripture says: ‘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’.

^28-29 As far as the Gospel goes, they are at present God’s enemies—which is to your advantage. But as far as God’s purpose in choosing is concerned, they are still beloved for their fathers’ sakes. For once they are made, God does not withdraw his gifts of his calling.
