Healed from painful shoulder problems through a word of knowledge

Dear Pastor George,
Today, the 26 June, I accompanied my daughter to the Miracle Service in the Glory Life Zentrum. I was only there in order to accompany her.
I want to tell you that I had terrible pain that morning in my left shoulder. This had been my problem for many years because of a strain on my left arm. After your “word of knowledge” I was healed today from this pain.
A question: How did you know that I was there, and how could you know what was wrong with me? When I asked my daughter this she said that this was a “word of knowledge”.
Kindest regards, Hannah
