Jesus' death is necessary as it satisfies God's justice and serves as a propitiation for the sins of His people.
The necessity of Jesus' death is rooted in the concept of atonement, as outlined in Scriptures such as Isaiah 53:10 and Romans 6:23, which states that the wages of sin is death. Jesus' sacrificial death was essential to satisfy God’s holy justice, serving as a substitute for His people. This means that Christ took upon Himself the penalty due for sin, thus providing what is known as propitiation—satisfaction of God’s wrath against sin. In fulfilling the law and becoming the ultimate sacrifice, His death is the foundation of the believer's justification and reconciliation with God, providing assurance that those whom He represents are saved from their sins.
