From The Improbability of God again. Page 383.
If there were an all-good and all-powerful God who could act in time, then we would have better evidence than we have…Why would such a God hide? Some theists answer that, if the evidence for God were stronger, believers would not need faith.
But why is that an answer? Why is that an objection? Why is faith taken to be a good thing? Why is it supposed to be a loss if we don’t need it? Apart from the obvious protective reasons – the obvious contorted explanations that theists offer to explain inconvenient realities such as God’s strange failure ever to drop by and say hello.
Is the idea that faith is – what – generous, gratuitous, loving? But anything can follow from that. You get epistemic chaos from thinking that way, and from epistemic chaos you get disaster. You could have ‘faith’ that a loving god wouldn’t let anything bad ever happen, and so do nothing.
It’s the same as the problem with claiming that we can’t know what all possible goods are but God can, so we aren’t in a position to know God is not good. Both of them are disastrous because both of them amount to saying that our best tools are not just fallible, not just incomplete, but fundamentally wrong. That’s a desperately bad, reckless, irresponsible idea, because we have to do our best. We have to. It doesn’t matter to us if there are infinitely wise benevolent powerful beings in some other part of the cosmos if we can’t get at them; we have to do what we can do, and if we don’t, we just make things worse. ‘Faith’ is dangerous, the idea that ‘faith’ is a good is dangerous, and the idea that what looks like pain and suffering is actually beneficial in some deeply hidden secret way is extremely dangerous. Some of the twisted things that philosophers of religion say are not just wrong but – anti-human.
