How do we know Jesus' sufferings were for our sins?

Jesus' sufferings serve a specific purpose in God's redemptive history. The Apostle Paul clearly affirms in 1 Corinthians 15:3 that 'Christ died for our sins according to the Scriptures.' The prophetic texts of the Old Testament, including passages like Isaiah 53 and Psalm 22, foreshadow His sacrificial death. Psalm 35 also illustrates Jesus’ earnest plea against the evil he faced, underscoring that his suffering was ultimately linked to the atonement for our sins. Thus, His agonies serve as the fulfilment of God’s greatest love toward humanity, establishing our salvation.
