Cofty, you said:
Are you seriously proposing that god cocked-up and didn't know about the tsunami until it was too late?
You're putting words in my mouth because you assume that I posite that God would do anything about if if he knew about it beforehand. I didn't say that.
Why did god not prevent the tsunami in 2004?
a) He didn't know about it
He has stepped aside, either permanently or temporarily [I don't know which] from interveining personally in human affairs. To know or not know beforehand about it is therefore irrelevant.
b) He left Jesus in charge so it was his fault
It's not Jesus' business to stop natural disasters, or to stop bad things from happenning to good people. It's up to Jesus to teach people to make the best possible choices in life, find comfort and courage in hope and to attain salvation in the heavenly realm.
c) Physical life is relatively unimportant compared to heaven
The importance of physical life compared with heavely life is indeed relative, but the fallacy of your reasoning is that such relative importance implicates the play down of human suffering. It doesn't.
In essence, my answer is:
d) It's not God's business to exempt human beings from suffering that has always existed in nature. It is God's business to help people to cope with said suffering and to find comfort in a hope for salvation into a better life outside the physical realm.
