while waiting for my family to finish riding jet skis, I got a word of knowledge for a back condition. I asked the two muslim men sitting near me (one from India, the other from Bangladesh) if either of them had a back problem. One had a lower back condition (my word was for the upper back) and so I prayed for him and the Lord healed him. I was able to share a bit more about my Christianity with them.
After about 15 minutes, I checked in again and there was still no pain.
