For a moment imagine that you have been diagnosed with terminal cancer. By the time the doctors figured out what you had it was too late. The cancer has spread and your options were exptremely limited. I can't imagine how that feels- to know that "your time" is on the horizon. If this were you, what would you do with the time you had left? How would you live today differently?
Not to be a big downer, but we're all "terminal." All of us are going to die. A person with a terminal prognosis just happens to know the window of when it may happen. None of us is guaranteed tomorrow. Only God knows. We all have an expiration date, but we live oblivious to when that will happen. How weird would it be if we had an expiration date tattooed on us from birth, like alot of items we buy at the grocery store!? It would probably drive many of us crazy to know when "our time" is appointed. Whether we are 32, like myself, or 80 we never think that we're going to die anytime soon. But wouldn't it make you live with more of a sense of urgency, to take advantage and appreciate every moment? If your date was October 5, 2008 what would you do on October 4? I think we all need to live like that today because it could very well be our last.
If you think about it, we're all on bonus time from God. Life is so short in comparison to eternity. We all need to make sure that we're ready for eternity because our time may come quicker than we know. (Cue "Live Life Like You Were Dying" by Tim McGraw)
