Nearer my God to ....

I do not like glib or trite sayings and the expression "There are no atheists on a battlefield" seems a way of getting your point across somewhat insidiously.
Not that the saying is entirely without merit of course, as many will have indeed turned to prayer in extremis. The real test is how many of these people keep the promises they have attempted to make to God; how many will keep to their part of a one-sided bargaining as the years go by.
Children sometimes ask me why prayers are not answered - again of course, we have a set response - "They are answered, it is just that the answer may be 'no'." - That also smacks as being a bit trite to me.
One response to their question which is not strictly accurate in any theological sense but does point them in a logical direction at least, is to compare with having money in the bank.
I ask them if you can take money out of a bank [forget ATMs, please] where you have no account.
The point is usually grasped pretty quickly - although one must remember to remind them that there can be some pretty mouth-watering deals to tempt you to open new accounts on occasion!
