today while walking into a restaurant, I noticed a Gulf Arab man in front of me and I got a word of knowledge for a headache in the back, left side of the head. After a few minutes, I asked this man if he had this problem. He did. Immediately he asked me, "how did you know"? I explained that it was by "revelation" from God. It wasn't hurting at that moment, so I gave him my phone number. I told him that when it came back he needed to call me.
