Waiting

I am sitting here waiting for the delivery man to come with our new fridge.  I am starting to get a little impatient because I know that he is coming, but I don't know exactly when.  I am prepared for his arrival and desire for it to be soon so that I can move on to the good stuff of putting everything back in our new fridge and arranging stuff in the old fridge and freezer.  

Isn't this kind of like waiting on Christ to come back again?  I know that he is coming at some point because that is made clear in the scriptures, but I do not know when that will be.  I don't know if it will be during my lifetime or after my death.  Sometimes I get impatient and want Christ to come back now because there is so much pain and suffering which I know will not be present when we are with Him in heaven.  At the same time, I hope that all are prepared for his arrival.  It gets me thinking about what I need to be doing while I am waiting to prepare for his arrival.
