I've never been much of a religious type... until I was in a serious car accident. When I was coming out of a month-long coma, I swear I could feel every prayer that people were saying for me. I don't really know how else to describe it, other than to say I could literally feel those prayers. Ever since then, I am a believer, and any time I am asked to say a prayer for a friend, I will take a moment and say one.
Done.
