How do we know that Christ's redemption is true?

The truth of Christ's redemption is grounded in the promises of God found in Scripture. Believers are told that Christ died not as a mere offer, but He died on purpose, fully intending to redeem His chosen people. This is also evident in how faith is bestowed upon individuals, enabling them to believe and embrace this truth. As stated in Romans 9, God's sovereign choice in salvation affirms that He loves His people, demonstrating the reality of redemption through His grace. Our confidence rests not in ourselves but in the faithfulness of Christ who has completed the work of salvation.
