'It is possible to waste your life. Few things make me tremble more than the possibility of taking this onetime gift of life and wasting it. Every morning when I walked into the kitchen as a boy I saw hanging on the wall the plaque that now hangs in my living room: “Only one life, twill soon be past, only what’s done for Christ will last.” And now I am almost 58, and the river of life is spilling over the falls of my days with tremendous speed. More and more I smell eternity. And oh, how I want to use my life well. It is so short and so fragile and so final. You get one chance to live your life. And then the judgment. I speak as a father who has children your age, and I am jealous with Jesus that they and you not waste your life.'  (http://www.desiringgod.org/ResourceLibrary/ConferenceMessages/ByConference/35/1858_Dont_Waste_Your_Life/ Don't Waste Your Life," from December 29, 2003)
