How do we know that Jesus came to save His people?

The purpose of Jesus' coming is explicitly stated in Matthew 1:21, where it is declared that He shall save His people from their sins. This statement is pivotal in understanding the intent of His incarnation. From the very moment of His conception and birth, Jesus was destined to be the Savior. The terminology 'His people' points towards the elect, those whom God chose for salvation before the foundation of the world (Ephesians 1:4).

Additionally, the assurance of His saving work is depicted throughout Scripture where Jesus Himself claims, in John 10:11, that He is the good shepherd who lays down His life for the sheep. This reinforces the guarantee that His mission was not tentative or uncertain; rather, it was determined and assured. The biblical narrative portrays various fulfilled prophecies regarding Christ, which not only validate His identity but also affirm that His purpose was meticulously woven into the fabric of salvation history. Consequently, the overarching narrative from His birth to His crucifixion underscores the certainty and effectiveness of His salvific work for those chosen by God.
