What does the Bible say about Paul's sorrow for the Jews?

In Romans 9:1-5, the Apostle Paul reveals his profound sorrow for his Jewish brethren who have not accepted Jesus as the Messiah. He emphasizes his genuine concern by stating, "I have great heaviness and continual sorrow in my heart." This anguish stems from their historical privilege of being God's chosen people, to whom belonged the adoption, the glory, the covenants, and the law, yet many have turned away from the truth of the Gospel and rejected the fulfillment of God's promises in Christ. This scripture illustrates Paul's heart for the lost and reflects the weight of responsibility felt toward those who remain outside of faith in Christ, pointing to the urgency of sharing the Gospel.
