What does the Bible say about the significance of Jesus' suffering?

The Bible reveals that Jesus suffered as a substitute for humanity, bearing the penalty for sin that we deserved. His suffering was not for His own sins, for He knew no sin, but rather it was vicarious; He took upon Himself our iniquities. This suffering was necessary to satisfy God's justice and to redeem His people from the curse of the law. The Apostle Paul expresses this truth in Galatians 3:13, stating, "Christ hath redeemed us from the curse of the law, being made a curse for us." This underscores the vital importance of His suffering in the salvation of all who believe.
