Wonderful things happen on Earth. Birds fly. Trees grow. Snow-capped mountains produce crystal-clear streams. Terrible things happen, too. Volcanoes. Tsunamis. Tornadoes and droughts. As with nature, so with human nature. We are all of us capable of being great saints or sinners. Often, we swing from one extreme to the other - so fast that we don't always even know which extreme we have swung to! Our circumstances can sometimes change just as fast. What has lately been looking bad, may soon start looking good.
