A bar called Drummond's (in Mt Vernon, Texas ) began construction on an expansion of their building, hoping to "grow" their business.
In response, the local Southern Baptist Church started a campaign to block the bar from expanding - petitions, prayers, etc.
About a week before the bar's grand re-opening, a bolt of lightning struck the bar and burned it to the ground!
Afterward, the church folks were rather smug - bragging about "the power of prayer".
