Time

How do you view your time?  Do you think of it as all yours, and if someone does something that you think messes up your plan are you upset?
When we think of time as our own, we can get irritable and impatient.  If you are standing in line at the grocery store and things are going slow, you might stand there tapping your foot angrily until it is finally your turn.  Or if you are in traffic because of and accident on your way home you get impatient and complain aloud to all the other passengers in the car.

We should not view time as our own, it is really God's time and should be used for Him and not us.  If things are not going exactly the way you want them to, don't let out on God or other people, but know that God is in control.
