Seems to me that theists are the one's with a story. Of course it's stories within stories but the point is that it is their story and the onus is on them to back it up.
Their main tactic is to simply repeat portions of the story which seem to fit the situation. For example, talking to atheists, there is a very short story dismissing them entirely with the, fool, who says, in his heart that there is no God.
I think that if we were talking about any other piece of literature, we'd all recognise that as a slogan. Actually I think that most people still do recognise it for what it is, but of course 'Bible-studiers' won't talk about what a great slogan that is, no, they are simply enlightening us as to the obvious 'truth' of the Scripture.(and 'happily' calling anyone who disagrees with it and them 'fools' in the process.)
Unhappily, if a person doesn't believe that the Bible is a special book with supernatural truths, he or she is unlikely to be impressed with this slogan and can see it is obviously just tit for tat, you call me a fool for being a magical thinker and I'll quote my magical book telling you that YOU are the fool! Ha!
Of course if you do 'study the Scriptures' you'll notice that it is chock full of characters having Godly experiences. I think that sooner or later you will have to come to the conclusion that it is drivel OR start wondering when YOU get to have some personal Godly experiences of your own.(not to mention seeking out Godly experiences of everyone else.)
The efficacy of prayer, the spiritual contact between a person and his/her God, is neatly circumvented by the idea that God has the option of fulfilling your wish, dismissing your wish or postponing(indefinitely) your wish.
In other words, if you believe that God is 'there', then he must answer prayers but(sadly) the answer comes in the form of a fulfilled wish, a 'hit' or an unfulfilled wish which is either an out and out miss(Grandma died) or perhaps not yet a hit(Grandma isn't getting better 'yet').
Pointing out that the efficacy of prayer would be the same no matter which God one prays to, or if prayer is directed at an inanimate object like an empty jam jar, is insulting.
Did you get that? The plain truth, the plain facts of the matter are an INSULT! Of course other Gods reference was insulting enough but the 'jam jar' thing was total sarcasm, insulting, demeaning and an attack on their spiritual/supernatural beliefs.
God is no better at answering prayers than an empty jam jar. The truth of this is lost in, and denied with, a hurricane of affront and loathing.
Seems to me that if an appeal to God is deemed necessary then 'things turning out alright' is deemed 'personal experience proof positive' that prayer IS effective. But the opposite isn't true. If things don't 'turn out alright' then God is forgiven. Did you get THAT one? God gets forgiven for not using his awesome powers to 'make things alright'!
The reality of God(in believers' minds) only depends on HIM occasionally 'making things alright' and the non-reality of God is exposed by 'things turning out alright' for people of differing faiths AND for non-believers too!
This obvious fact is COMPLETELY and WILLFULLY ignored by all true believers.
