That, at face value, appears to be incredibly "vengeful". It's almost as if it's saying ... I'm so angry I couldn't forgive you in a million lifetimes for what you did, so you're gonna shed some blood for what you done. It's a frightful thing to be delivered into the hands of an angry god. I wonder, I mean I truly wonder if that's how it is.
I think about my child and just the thought of someone doing harm to him enrages me to the point of near madness, then I think about what happened to Jesus and how his mother must have felt. A frightful thing indeed. Then I also see a more peaceful side to it. A monthly cycle once viewed to be a curse that only happens to woman. Without the shedding of blood there is no forgiveness of sins. And some wonder why I call them god.
Wow. Ummm, no.
You've got this picture entirely messed up.
First off, women don't "shed blood" the lining of their uterus thins. It thins because for that month the uterus is not needed to be thick, because there is no pregnancy. What you are actually seeing is less blood shed, and more a dam lowering its gates because that excess collected needs to release. You see, this blood has hormones the body doesn't need any more.
The whole deal where Abraham sacrifice his son, then proceeds to sacrifice his own son... Unfortunately, you have the story wrong.
You see, the first thing God did here was offer an animal instead of Isaac. Of course, you don't feel better about this story as it still looks like a cruel test. Until you realize, that God effectively created/summoned this animal simply so Abraham wouldn't have to offer his own son. God offered his own lamb in place of Isaac.
Despite the Jews viewing a woman's cycle as an "unclean period" (hey I never said these people were perfect) blood was used in the ritual/magic trick whereupon the sacrifice of an animal turned cloth white ( I'm guessing more the magic trick part, but God did seem to do nore miracles in those days). This was intended to remove sin, as a practice of atonement. But I want you to think about all of these animals killed. The people of Israel began to lose connection with the significance of what they were doing. "It's not my child, after all" is the general attitude as they callously put to death a sheep or a goat. So you begin to see God say things through his prophets like "I do not delight in burnt offerings." The people of Israel paid this no mind. Until God gave his only Son as blood sacrifice for atonement of sins, and they no longer had a Temple to perform sacrifices in.
Before we discuss God giving his only Son, I want you to think about this. Around the world, babies are getting aborted every day. This is a sacrifice that has no purpose other than to remove a mother's shame. So while you can be mad at God for now, you must also be mad at the mothers who should do such a thing. And in some cases, the fathers that pressure them into this, to hide their affairs.
Get a nice image of this.
Got it? Good, now let's review the Trinity. Father, Son, and Spirit are all God. This means, that you will find marks on the hands of God as well as his Son. In order to wipe sins away, God himself was put into the path of harm. God became the Sacrifice for the sake of these people who would continue to kill innocent animals for their guilt.
Now, remember that vivid abortion picture I gave you? I want you to throw it away. Because this is not a child sacrifice at all. It's the decision of humans to kill this son. Jesus says "forgive them for they know not what they do" but he accepted his death. Instead of a abortion, I want you to think of a child put at the doorstep of a family. Jesus was basically God inside a human body, adopted by humans. So we have this nice sweet picture of a doorstep baby... only the doorstep is Jeffrey Dahmer. No, Mary and Joseph were decent, but the world Jesus was adopted into was cruel. The priests, the pillars of the community gave him over like all those other animals, to be tortured and killed. Whipped until he bled, made to wear a crown of thorns. And then hung above others on a pole to slowly die.
God isn't some jerk who demanded child sacrifice of his son. Humans did the sacrificing, and God did the suffering.
