How do we know that Christ's death was for His people?

The doctrine of particular redemption or limited atonement is rooted in Scriptures such as John 17:9, where Jesus states, 'I pray for them; I do not pray for the world but for those whom You have given Me.' This emphasizes that His sacrificial death was specifically for the elect, ensuring their salvation. Furthermore, Romans 5:8 reiterates God's love manifested through Christ's death for the ungodly, demonstrating His purpose in dying for a particular people—those chosen in Christ before the foundation of the world.
