When it comes to knowing one’s purpose, Jesus knew that He was born to die for the sins of the world and rise from the grave three days later. He knew victory over death was ahead of Him and that He would be restored to His full glory at the right hand of His Heavenly Father. But He also knew that the path to the empty tomb and His exaltation would lead Him through the shame and humiliation of the cross.
Roman soldiers had no affection for the Jewish people, so being given permission to mock and crucify a Jewish man was an opportunity they relished and took a sick pleasure in executing. As such, they intended to fully humiliate Jesus before nailing Him to the cross. Part of the humiliation involved mocking Jesus as a king. This is why they clothed Him in a purple robe or cloth, which was the color of royalty, and made a crown of twisted thorns, which was intended as a mock crown but also to inflect pain when they pressed it down upon His head.
And with that, sometime between 3 and 4 p.m. on a Friday, Jesus won the victory over sin. He was the perfect sacrifice, the Lamb of God without spot or blemish who takes away the sins of the world. But Jesus did not come only to defeat sin, He also came to defeat death. To do this, Jesus had to fully experience death, so the spirit of Jesus descended into Hades, and into the realm of the righteous dead to lead captivity captive.
