I've been told that two or three times by a certain young priest with a German last name who likes Seinfeld and has awful taste in Star Wars films! He's starting to repeat himself! The "bam!" effect only works once. After that, meh...
I've seen the Iveron icon 4 times or so. While I marvel at it oozing myrrh and wafting incense out of it that smells like roses, I've never actually witnessed it heal anyone or help anyone. I KNOW that it does, just never saw it. With the shoulder, back, and neck pain that I suffer with (I rarely talk about it on here; it is intense and hellish), I would love such a healing. I prayed that request before the icon. It just wasn't in the cards. Maybe someday....but I don't doubt its power!
