So I had him put his hand on his mouth where the pain was. We quickly released the Kingdom and commanded the pain to leave. Then we gave him a task - to go eat/drink something cold and come back to tell us what happened. After about 10 minutes, he comes back looking really puzzled (which we knew was GOOD). I asked what happened. He said he drank something cold and there wasn't a problem, but he didn't believe it could be possible so he had to then go and eat something cold to really test it out. No more pain! He was seriously touched - it was awesome to just tell him about the Power of the Holy Spirit and the nature of God's Kingdom.
