What does it mean that Christ came to save the preserved of Israel?

In Isaiah 49:5, the phrase 'to restore the preserved of Israel' signifies God's commitment to save His elect, those whom He has chosen before the foundation of the world. This remnant represents a selection of individuals who, regardless of the larger group's rejection of Christ, will inevitably come to faith. The notion emphasizes God's covenant faithfulness and the effectiveness of Christ's redemptive work on the cross. Unlike a mere offer of salvation to all, the preservation of God's elect showcases the certainty that those God intends to save will be brought to Him (Romans 8:30).
