What does it mean that Jesus saves His people from their sins?

When Scripture states that Jesus will 'save His people from their sins' (Matthew 1:21), it underscores the intention behind His coming to earth. This declaration affirms that His mission is not a universal salvation but a specific one aimed at those whom the Father has given Him—His elect. This aligns with the historical Reformed understanding that salvation is particular rather than general, as seen in passages like Ephesians 1:4-5, where Paul speaks of God choosing individuals for adoption before the foundation of the world. Thus, the work of Christ is effectively redemptive, securing not just potential salvation for all but complete salvation for those He came to save.
