I have a story to share that I am still processing a week after the fact. Last Sunday a friend and I were leading worship at our church. We were rehearsing in the sanctuary prior to the service. Apart from the two of us, there were two guys working the sound board and a friend setting up the communion table.  Barb and I began to sing the song "He Shall Reign." As we did, I felt how important this declaration was in these times. Suddenly, I realized we sounded great. (Not something I usually think. We are not great singers, just bringing our two mites to the offering box), and then I realized why: a third voice was singing with us. It sounded like a women's voice. It was beautiful, in key, and in time. Clearly not mine, nor my friend's. I looked at the woman setting up the communion table-- she wasn't singing. I looked at the guys. They were chatting quietly about the sound board. I looked at my friend. She was singing, but had paused to take a breath, yet this beautiful voice was still singing. I began to wonder if I was imagining things, but after we finished the song, my friend turned to me and said  "Did you hear that third voice?" "You heard it too?" I cried. We asked the three people in the sanctuary if they had been singing. No one had. We were in awe. A few days later, just to be sure, I asked a musician friend, who has a band and knows sound boards, etc., whether an accoustic anomaly were possible, given our sound set-up. He said no, he couldn't imagine how a voice, in synch with the guitars and our voices,  could suddenly appear, given the simple equipment we had.  He is not a believer.  I thought he might try to give me some rationale, materialistic explanation. Instead, he seemed to take it in with some wonder.
His eyes widened and he said, something like, "Oh!" or " woah."

If you know Jason Upton's song "Fly", it wasn't like that. In that song, an angelic voice is humming, or singing, without words, and it is deep. In our case, we heard all the words, and the voice was a high alto, beautiful, with perfect pitch. Here's the song we were singing. (We were not recording, sadly, but you can check out the song sung by its songwriter on Band Camp: He Shall Reign by Tom Wuest.)
