I think sometimes when we think about God. When we say things like ‘God will take care of it,’ or ‘God will always make sure everything is alright,’ there is this hesitancy, this discomfort, because there times in our past, in all of our pasts, where that just wasn't the case, where things didn't work out so well. There are times when we can look back and think ‘wow, where was God then?’ For me, the biggest challenge is maintaining faith in the God concept in spite of mounting evidence that he either doesn’t exist at all, or just doesn’t care.
