While attending a conference, I returned to my hotel room late one evening. The overhead light outside my door was burned out and I had       finding the keyhole. When I       to open the door, I       around the wall for a light switch. I found a plate where a switch was       installed... but no switch! 
Not discouraged easily, I remembered       a lamp by the bed when I deposited my luggage      in the day. I found the bed in the       and then the lamp, but when I switched it on, nothing     ! I thought that perhaps if I opened the curtains I might be able to use whatever light comes in from the       to find another lamp. So I  my way slowly across the room to the curtains and... no drawstring(拉绳)! I finally stumbled(跌跌撞撞地走)around        I found a desk lamp which actually     !
That evening I discovered in a whole new way just how dark the world       be and how   necessary light is! But even more necessary than       light is the light that shines from people --the light of       and faith. Because, for many people, the world is a dark and       place. For someone today just may be stumbling in discouragement or sadness or fear and in        of some light. So let your light shine. Whatever light you       may be a beacon(灯塔) of hope and encouragement. And if you feel that your light is       a candle in a forest remember -- there isn’t enough darkness in all the world to       the light of one small candle.
