You don't know that by looking at the scene from outside, but Jesus tells us what is going on inside. What looks like bloody sacrifice is really just self-emptying love. In Matthew's gospel it says that people came to Jesus and asked him where is God. So Jesus answered them. OK, I'll tell you.
Someone finds a treasure and hides it in a field.
Then in his joy he goes and sells everything he has and buys that field. They didn't so, he tried again. A merchant searches for fine pearls. On finding one pearl of great value, he went and sold all that he had and bought it. When we talk about God, we are talking about finding something, giving something up and receiving something.
