That's what I meant when I said "even if we have to work to make them useful to us".
But we do
all the work. It's the same for anything where you might consider thanking God. It always turns out that it's actually humans doing the work.
It's the mirror of the situation where something bad has happened. You're quite happy to say that the bad things done by humans are all their own work. So why do you begrudge the same courtesy to humans that do good things.
Conversely, if you want to ascribe the good things we do to God, you must logically also ascribe the bad things to God. If God provides us with food and clothing, he also provides murderers with guns and knives.
Are you trying to avoid admitting that God is good?
No, I think you are trying to avoid admitting that your god is bad.
