In the spirit of trying to increase faith, please post examples of prayers you've personally seen answered.
I'll start with two:
1. I prayed for a mentally ill friend of mine to be healed from it, and he was. Five years ago he was deeply depressed and suicidal; today he's happy and healthy.
2. I prayed for my wife - when she was still dating someone else. It was very interesting because when I prayed for her, I had a distinct sense that God said to me, 'yes, you'll have her, but not yet.' About a month later she turned me down for a date (she was dating someone else). About 18 months later, we were married. (And I didn't even do anything sneaky to steal her from her old boyfriend, except maybe the prayer).
