James 4:13-17

"Now listen, you who say, 'Today or tomorrow we will go to this or that city, spend a year there, carry on business and make money.'  Why, you do not even know what will happen tomorrow.  What is your life?  You are a mist that appears for a little while and then vanishes.  Instead, you ought to say, 'If it is the Lord's will, we will live and do this or that.'  As it is, you boast and brag.  All such boasting is evil."

I'm going to retranslate that into the "Peter just had an interesting weekend" version.

"Now listen, you who say, 'Today or tomorrow we will go to Chicago and then Milwaukee, go to a wedding, and return home.'  Why, you do not even know whether or not your car's coolant hose will crack before you get there.  In addition, the tow truck may be delayed such that you cannot get your car fixed until Monday, forcing you to depend on a friend's relatives for a bed and to take the train home early the next morning.  What is your life?  You are a mist that appears for a little while and then vanishes.  Instead, you ought to say, 'If it is the Lord's will, we will live and go on a road trip to celebrate an old friend's wedding.'  As it is, you boast and brag.  All such boasting is evil."

Apparently I'm not quite as in control of my life as I like to think.
