How do we know that the sacrifice of Jesus was necessary for our salvation?

The necessity of Christ's sacrifice is founded on the nature of God’s justice. Romans 3:26 emphasizes that God justifies the sinner while remaining just Himself. The death of Jesus was not arbitrary; it was ordained as the only means by which God could righteously forgive sin. In Gethsemane, Jesus prayed earnestly about this cup of suffering, indicating that this was the path appointed for Him. Without His death, there would be no atonement for sin, as established by Hebrews 9:22, which states that without the shedding of blood, there is no remission of sin.
