What does the Bible say about the death of Jesus?

According to John 12:24, Jesus states that unless a grain of wheat falls to the ground and dies, it remains alone, but if it dies, it produces much fruit. This metaphor highlights the necessity of Christ's death — He had to be crucified, buried, and then rise again to satisfy the justice of God and honor the law. Without His sacrificial death, there would be no remission of sins, as emphasized in Scripture. His death was not an end, but the beginning of a spiritual harvest that brings together people from every tribe and nation into the family of God.
