Something that came to me in Sunday School this past Sunday:
You know how people will say to you, "Live as if it were your last year or your last week or your last day. What would you do differently?" Usually, pastors and the like will mention how you need to be soul-winning because this very well might be your last bit of time, you never know when Jesus will come back. So, people will tell you, "Live as if it were your last."
This is a pity. It shouldn't take such an extreme hypothetical idea to charge people into living for God and into living well. We each need to be truly thankful for the life we've been given and the recourse's we have at our disposal. There are so many opportunities, and if the only thing that wakes us up to this is someone waving the thoughts of "your last day" in our faces, we are lazy bums who should give our lives to someone else who wouldn't waste it. "The last chance" isn't the only day worth living. Jump at a chance.
