Why is Christ's sacrifice essential for believers?

Christ's sacrifice is the cornerstone of salvation as it addresses the profound issue of sin that separates humanity from God. According to 1 Peter 2:24, He bore our sins in His body on the tree so that we might die to sin and live to righteousness. His death serves as the ultimate atonement, fulfilling the requirements of the law and the justice of God. Without His sacrifice, there would be no means for believers to be reconciled to the Father. Furthermore, through His resurrection, believers are granted new life and the assurance of eternal fellowship with God, as seen in Romans 5:8-10, demonstrating that we have been saved through Christ’s death and will be saved in His life.
