What does the Bible say about the purpose of Jesus' crucifixion?

According to Scripture, Jesus came into the world to fulfill God's redemptive plan by being crucified. In John 12:27-30, Jesus expresses His troubled soul at the thought of bearing the sin of His people, which is central to His mission. He was the Lamb of God destined to take away the sins of His people, as highlighted throughout the Gospels. His crucifixion was not merely a tragic event; it was the culmination of God's sovereign plan to glorify His name through Christ's sacrifice, fulfilling the prophecies of the Old Testament. In Isaiah, for instance, it is written that the Messiah would be stricken for the transgressions of God’s people. This act would provide not just a means of forgiveness but the ultimate basis for the believers' righteousness before God.
