What does it mean that Christ came to save His people?

The phrase 'He shall save His people from their sins' (Matthew 1:21) encapsulates the essence of Christ's redemptive mission. Christ came into the world with a specific aim: to redeem those whom the Father gave Him. This promotes a clear understanding of salvation as a work of God, not a mere option based on human choice. It affirms that the atonement is effective for the elect; those for whom Christ dies will be saved, as expressed in His high priestly prayer in John 17:9, where He states He prays for those given to Him, not the world. This underscores the effectiveness of Christ's sacrifice, ensuring that all whom God has chosen will come to faith and ultimately attain salvation.
