In a culture as shocking as this one, our anger can easily be aroused.  But is it wrong to be angry with a sinful world?  God has made us with the capability to have righteous anger and unrighteous anger.  Our passions can often seem sinful in regard to our anger.  Praise God, the Gospel can change our passions and desires.  When we get angry, we have an example to emulate.  When we feel like we've been done unjustly we must remember that we have been called to be image bearers of God.
