convinced & despised

Tomorrow's Gospel reading is from Luke 18 -

The Parable of the Pharisee and the Tax Collector -

Here is the first verse (NAB):

"Jesus addressed this parable to those

who were convinced of their own righteousness

and despised everyone else."

Being convinced of being right,

can lead to setting myself above others,

which can lead to despising others?

Whoa....

I can't even begin to count the areas in which

I'm convinced I'm right!
