I just prayed for a customer care agent over the phone who was trying to sell me on a magazine subscription. Which I turned down.
As we were getting off the phone I had a word of knowledge about a condition in her neck and right shoulder. She was taken back and didn't really know what to do or say. After I prayed she said it was much better. You could tell she was a bit nervous because she wasn't expecting that.
Remember, we are called to put Jesus on display with love and power even when it's a customer care agent trying to sell you on a subscription ; )
