A number of years ago researchers performed an experiment to see the effect hope has on those undergoing hardship. Two sets of laboratory rats were placed in separate tubs of water. The researchers left one set in the water and found that within an hour they had all drowned. The other rats were periodically lifted out of the water and then returned. When that happened, the second set of rats swam for over 24 hours. Why? Not because they were given a rest, but because they suddenly had hope!
Those animals somehow hoped that if they could stay afloat just a little longer, someone would reach down and rescue them. If hope holds such power for unthinking rodents, how much greater should is effect be on our lives.
