I'm not interested in probabilities on this thread. Not all prayer is answered, there may be all kinds of different reasons for that, but that's not what I'm interested in. I just want to present cases that suggest prayers that did get answered.
The point is how is anyone supposed to validate the efficacy of prayer? I prayed to God, I got what was requested, therefore God fulfilled it. The inverse is I prayed to God and nothing happened. We can't ask all the dead who prayed for a miracle and God didn't deliver. I'm sure that 90% of the people in the Trade Towers uttered a heartfelt and earnest prayer out of pure desperation... right before all of them died and no prayers answered. What's your metric?
Seems like you're purposefully excluding all the instances where people were savagely slaughtered on Forensic Files and focusing on the handful of lucky bastards that lived. What of the hundreds of others?
