Who are the people Jesus came to save?

In Matthew 1:21, it states that 'He shall save His people from their sins.' This implies a particular redemption; Jesus did not come to save everyone indiscriminately but rather those whom God chose and gave to Him before the foundation of the world (Ephesians 1:4-5). The terms 'His seed' and 'His sheep' used in Isaiah 53 and John 10 reveal that these people are the elect and the church, the bride of Christ, whom He purchased with His own blood. This doctrine reassures believers that they have a sure and definite Savior who accomplished their salvation.
