cofty: The answer of the catolic church is according to pope john paul II., Yes, God is in a certain wise powerless and he stands on the side of the suffering ones like the biblical "man of sorrows". I ask for patience because english is not my motherlangue.
Furthter its seems to be that the whole creation - and men are part of creation expecially if we think of the natural laws that lead to human life, and the natural laws that regulate our life and our pain - has the same fate as the other creation living and non living, and as animals.
Sparrows: Jesus said that God knows about the fate of the sparrows not because he was anaware of their actual lifesituation, but to show that God stands on our side, that God is our only hope for salvation, and in the jewish-christian thinking context, that fate of mankind is always the fate of the whole cosmos.
Jesus'suffering was not a necessary quanititive asset to be paid to a God or the Devil as ransom, but is the merely the conclusion of a devoted life, thus his suffering is the same suffering that we face , it is a suffering "with us together", a kind of solidarity. like a brother gives his life for his sister or similar.
I looked up more infos about that matter and will write later beginning what the hebrew sprictures tell about suffering.
