Hopefully the title makes sense in its own right. One paradox I try to remember which works quite well is this: When it comes to prayer, if you pray for something but fear it won't be acted upon by infinite intelligence, your prayer will have been in vain.
This means that you are to enter prayer (or wish/hope) with no fear of anything going wrong, so for you to be confident in everything turning out alright, you must eliminate doubt, then your wish will turn out.
It's hard to explain, but I hope this could help anyone who may need it, or at least spur you on a bit longer.
Does anyone else know of any such logic paradoxes that do away with fear?
