He wasn't the guest minister... This thing normally happens... An artist can just appear from nowhere and you have no option for them to minister... That's what happened
I was personally there in the auditorium. Nicholas just walked in unannounced and sat in the congregation. The Prophet took notice of him and acknowledged him, requesting him to come and sit at a designated place for guests. He just asked Nicholas to minister and he did. It actually delayed the service a bit because it wasn't planned. I received my prophecy right after the song ministrations.... It was an awesome time
