What does the Bible say about Paul's longing for Israel?

In Romans 9, the Apostle Paul reveals his profound sorrow and yearning for the salvation of Israel. He articulates a heartfelt desire, stating he would even wish to be accursed for the sake of his fellow Israelites, indicating the depth of his love and concern for their spiritual state. Paul acknowledges the privileges experienced by Israel – their adoption, glory, covenants, and the law – yet he understands that not all Israel is truly Israel, as not all who are descended from Abraham are children of God. This longing reflects his recognition that true salvation is found only in Christ, whom many have rejected, leading to a painful burden in his heart for their redemption.
