At one time or another, during times of personal struggle or loss, we've all heard people tell us they would “pray for us.” Just an expression, I'd always thought, until I felt the power of that sentiment when it is offered, and meant, by tens of thousands of people. The feeling is overwhelming; I have no doubt that being on the receiving end of so much spiritual energy has gone a long way to sustain me over the last couple of years. I no longer underestimate the power of prayer.
