Perhaps I should have been clearer.
I'm not talking about the afterlife version of hell - I'm talking about the living hell of pain, disability and despair which incurable conditions force on living human beings.
You were saying:
if God prevented humans from experiencing any bump or bruise, sickness or sin, we would be weaker because of it.
I was saying you are not being honest enough. You should be saying:
if God prevented humans from experiencing any excruciatingly painful, lifelong incurable condition from which there is no escape and for which there is no cure, or sin, we would be weaker because of it.
You'd still be making your point, but at least you'd be being more honest about it.
Could there be any greater conceit, than for someone to believe that the universe has to be simple enough for them to be able to understand it ?
