Running Out of Time?

    Does anyone else sometimes feel really, really rushed? Not just in a particular activity, but in everything? Like there's always a clock ticking down, draining away time to accomplish things that you really, really, really want to get done? Like time will run out at any moment?
    I'm talking about the fear that the Rapture will come before a person has done all the things the Lord has called them to do; be it a project, or another kind of goal in life. I've been having this kind of worry recently, particularly when I consider how much time I spend procrastinating or investing precious time on less important things. The idea that all this wasted time will accumulate to the point where I no longer have enough time to finish the work before the Rapture tangles me--and surely a lot of others--up inside in knots of nervousness and guilt. And it's really a conflict in the mind too, since we know that fear and worry aren't of God.
    But when one really thinks about it, oversights aren't of the Lord either.
    And in that, there's hope! God doesn't notice anything too late; He's all-knowing and infinite. Before He created any of us, He knew us and our lives inside-out. He knew exactly how much time it would take us to complete a work, even accounting all the time we might spend procrastinating from that work. From the very beginning, He's known just how many hours it'll take for the jobs to be finished, so surely He must have things planned out so that even with occasional bouts of procrastination, the good, fruitful work will be completed in time.
    Not to say that it's okay to be lazy, having the mindset that we have all the time in the world; but the fact that God's gracious enough to grant us all the time we need in spite of our lapses in focus is a real comfort. It's motivating, calming, and it gives a real hope that it's never pointless to keep working on the work God has given us to do. It puts away the fear that time is going to run out and there's nothing we can do about it.
    What do you think? Do you ever worry about the clock striking twelve too soon? Does this idea about God's foreknowledge granting us enough time, wasted hours and all, sound right?
