How do we know that Christ died for our sins according to the Scriptures?

In 1 Corinthians 15:3, the Apostle Paul states, 'For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures.' This underscores that Christ’s sacrificial death is not an arbitrary event but a fulfillment of Old Testament prophecies and writings that point to the necessity of a savior to atone for sin. For instance, the Day of Atonement rituals in Leviticus demonstrate how God established a means for His people to be reconciled through the shedding of blood. Christ embodies this requirement perfectly, as He is the ultimate Lamb that takes away the sins of His people, as foreshadowed throughout the Scriptures.
