How do we know that Jesus came to die for our sins?

The Gospels make it clear that Jesus came into the world with the primary purpose of dying for the sins of His people. In John 10:11, Jesus states, 'I am the good shepherd: the good shepherd giveth his life for the sheep.' This is not merely a claim of martyrdom but a declaration of His intent aligned with God’s covenantal purpose. Throughout His ministry, He foresaw His death and often spoke of it in terms of fulfilling prophecy and establishing a new covenant through His blood. The very fact that He was willing to face betrayal, agony, and death underscores the certainty of His mission. The heart of the Gospel is that His sacrificial death secured the salvation of those whom the Father had given to Him, ensuring that through faith, they would receive eternal life.
