Pride can get a person into a heap of trouble. This particular verse brings up just one consequence of pride--Contention.
When was the last time you got into an argument with someone? What could have stopped that argument in it's tracks?
Let's look outside ourselves...perhaps in your church, school, or community. Is there something that is being argued? What is the root of that argument? Perhaps a change but one side is too proud of their past and 'how we've always done things' to allow room for change?
No matter the age--from toddler to adult; no matter the group involved, from siblings to Senators...contention ALWAYS begins with pride.
The opposite of pride--humility.
