Why did Jesus emphasize His need to suffer and die?

Jesus made it clear that He must suffer and die because His mission was centered on the salvation of His people. His suffering was not random; it was a divinely ordained necessity to address the demands of God's justice against sin. By teaching His disciples about His impending death, Jesus aimed to prepare them for the reality of His sacrifice that was needed to establish the new covenant and secure eternal life for those who believe in Him. His obedience to death was the ultimate act of love and fulfillment of God's redemptive plan, making it imperative for Him to accomplish this work prior to His resurrection and reign as King.
