 Why does the spilling of someone else's blood save us? Why is that so critical? And taking that even to the cross, Christ poured forth a lot of blood. We know he shed it in the garden. We know he swept a lot. We know that his body was torn apart during the scourging and the crowning, and he lost massive amounts of blood. He hung on a cross. A pinprick, one drop of the Lord's blood would have been enough for us, right? So why is this spilling of blood so significant to God?
