"Without the shedding of blood ..."

A quote from this week's lesson exposition:

Though many have called the blood sacrifice of Jesus gory and unnecessary, the Scriptures teach just the opposite. “Without the shedding of blood there is no forgiveness” (Hebrews 9:22) is stated without equivocation.

I am finding more and more that there is sense behind the laws given us in the Bible. As I read this statement, I wonder: Why? Why would forgiveness require the shedding of blood? And does it truly depend on "the blood sacrifice of Jesus"? Isn't a compassionate God free to have mercy on whom He will have mercy? Is He bound by some incomprehensible cosmic rule that blood must be shed before He can forgive?

A couple of thoughts along this line:

1) More intuitively obvious than bloodshed seems to be the requirement for recognition of the need for forgiveness before forgiveness can be received -- not because God isn't willing or able to give it but because the offender doesn't notice it being offered. If I don't realize that I need to be forgiven, God's offer of forgiveness is simply puzzling to me. Perhaps it takes a wound (to someone or something) deep enough to draw blood to reveal to me how desperately I need forgiveness and prompt me to receive it into my life.

2) Jesus' death brought forgiveness for others. Perhaps the full impact of sin isn't clear to us without seeing the ultimate effects of that sin in putting God Incarnate to a bloody, tortuous death. We weren't in Jerusalem that day, but we have all stood in the place of those who rejected Jesus and called for his death in order to get rid of him.

3) Is there figurative bleeding involved every time we extend forgiveness to others? Do we have to die just a little in order to let go of the wrongs done to us? Does that inner death give us a glimpse of what God sacrifices when He forgives?

I'm not sure there are any firm conclusions here, just some thoughts about the how and why behind this call for "the shedding of blood" in connection with forgiveness.
