Here are some images and video from one particular afternoon when my worship team was leading the two hour worship and prayer set. Someone felt pain in her knee unexpectedly and felt we needed to pray for anyone with knee problems. Two people came to the front and we surrounded them with prayers. One of them got really excited and told us the pain he normally feels had left.
He then prayed for the other person experiencing knee pain... After they experienced God's touch, there was much rejoicing :)
When we pray for nations or issues, we break up into small groups or get in line to pray over the microphone. Here is an image and video showing both!
