I prefer to say that God always achieves his goals. However, that doesn't mean there are no costs to achieving those goals. You want to reduce it to a dry mathematical formula. It is not. First, we are made in the image of God, which means that like us he can feel emotion. The issues with humanity undoubtedly have created sadness for him, even though he knows humanity will ultimately will be as he intended, this knowledge doesn't mitigate the emotion he felt, the price he paid. Now, to Christ, again, you totally fail to understand the scope of who He was as a human, and what he experienced. He knew, as one third of the Godhead, before the task, that he would succeed. He becomes a human for a very specific purpose, and in doing so is trapped in a body that feels pain, hunger, thirst etc,etc,etc. Imagine yourself diving into an 8 feet deep cesspool, and staying there for 33 years, for someone else, would you be making a sacrifice ? It was undoubtedly worse for him. He had to deal daily with the totally corrupt and broken world, for a perfect being, wouldn't you consider this a sacrifice ? Now to the cross, which you seem to feel was a piece of cake. Lets see. Of course as a human he was humiliated and spat upon and beaten, I wouldn't have blamed him if he said "I've had enough" and returned to his proper state and place, but he didn't, this wasn't a sacrifice ? He always had a direct connection with the two other points of consciousness of the Godhead, primarily his 'Father". This connection was severed upon becoming a human, and everything was filtered through his humanity, he probably felt isolated. On the cross, he felt the pain and all the rest, and when the full burden of humanities sins was placed upon him, his Father by nature severed the connection they did have. That's why He shouted " my God, my God, why have you forsaken me ?" So, there was no risk in his mind, no fear of death ? Feeling totally forsaken by the one who would bring him back to life ? He was in human form, and felt anxiety, dread, fear, but he carried on. No sacrifice there ? He went in to death with these feelings, with only his faith that God would do as he said. No sacrifice there ? The entire life and death of Christ was a sacrifice, given freely so that the perfect mercy of God and the perfect justice of God were re established, solely for the sake of................................................you, if you accept it.
