What is the significance of Christ being pierced on the cross?

The piercing of Christ on the cross serves as a profound fulfillment of prophecy, specifically noted in Zechariah 12:10. This event affirms Jesus as the ultimate sacrificial lamb, whose death not only served to atone for sin but also to reveal the depth of God's love for humanity. The spilling of blood and water upon His piercing has rich theological implications, representing both His physical suffering and the cleansing from sin that flows from His sacrifice. It also invites a response of mourning and repentance, acknowledging the gravity of sin that led to His death.
