Heated a 10,000 sq ft sanctuary for two months on an empty LP fuel tank in the Middle of Winter

With it being Sunday morning, if God did not do a miracle we were going to be all cold through the service. The small group of people I had at the time was hardy people, but I did not want them to experience freezing in the service.
I went into the church and simply turned on the heaters by Faith. (We had been smelling the LP and that meant the tank was empty, the gauge on the tank also said it was empty being all the way down in the red) I simply said: okay Lord here we go.
Surprisingly the heaters came on with that lovely blue-yellow flame. When the congregation came into the service, I told them the miracle. I had them all march with me out to the tank through the snow so they could see what God was doing. For the next 2 ½ months everybody in the church would go and look at the empty gauge on the tank to verify that God was doing a miracle. Our church was heated by an empty LP tank for 2 ½ months.
