WOW - moving right along here…
Time for a little OP interjection here…
For me both issues are in play. Certainly the things that Alan is referring to are very real and have more than a little potential to do a lot of damage to one’s faith.
But more generally - and speaking to CrimsonThorn’s point…Yes - technically the statement IS correct, but it is misleading and frankly redundant. (IMHO)
It’s misleading because “never known to fail” conjures up in the mind great confidence…like there are just tons of people who have said this prayer, and every one of them received what they prayed for - had their specific request granted.
This is why I asked in the OP, where are the studies and statistics to back up such a statement.
Now - As you say prayers are always answered…Well then that makes the statement redundant - so why say it at all?
Peace
