that can debated:
but that doesn't change my rebuttal to your post:
What is your answer
Suffering caused by whom?
Suffering at the hands of....?
Suffering due to the consequences of Sin.
My point?
If you smoke, you get lung cancer. If you eat McDonalds every day you will be 800 pounds, Diabetic, with heart disease, etc.
If you sin, there are spiritual consequences to that. The way I see it, the consequences of sin--are due to the nature of sin itself, just like the consequences of living an unhealthy lifestyle are inherent in the lifestyle. Sin--is its own punishment because of its very nature. Thus, I am not sure that the wrath of God due to sin is something active on God's part, so much as God's wrath for sin---is in the nature of sin itself given who God is.
This means---that when Jesus assumes suffering and death--the consequences of sin, he is suffering the wrath of God, yes---but not in the sense that the Father is literally pouring out wrath on His son instead of us. What Jesus is doing in suffering the consequences of sin is bringing the divine power of God to those consequences and in so doing transforming them.
The Protestant view of the cross--strikes me--as analogous to saying that---when you don't listen to the doctor and you keep smoking---lung cancer happens as a result of the wrath of the doctor. The doctor is punishing you for not listening to him. God the Father would be analogous to the doctor, the patient with lung cancer the sinner who didn't listen. Jesus would be analogous to someone who says to the doctor--"I never smoked, but I will accept getting lung cancer on the smoker's behalf and I will take on that punishment" and the doctor agreeing to that.
