How do we know God's purpose is fulfilled in Christ?

The fulfillment of God's purpose in Christ is integral to the sovereignty of God's plan for salvation. As stated in 1 Peter 1:20, Christ was 'foreordained before the foundation of the world.' This indicates that God's intent to redeem humanity through Jesus was established prior to creation, emphasizing that salvation is not a reaction to human sin but a part of God's eternal decree. Additionally, scriptural prophecies throughout the Old Testament culminate in Christ's life, death, and resurrection, fulfilling God's redemptive plan and ensuring that none of His chosen people will be lost but will be gathered in glory at the end of time.
