But God forbid that I should boast except in the cross of our Lord Jesus Christ, by whom the world has been crucified to me, and I to the world. Galatians 6:14

Boasting is ugly.  Many people spend their entire lives accruing accomplishments  like a resume that no one will ever read.  As followers of Jesus we are to be so enamored with Him and His accomplishments that we are freed from our own desire to impress others with our accomplishments.  When we understand that we have died to the world, we are free to understand that we are no longer obligated to attempt to impress the world.  The mark of our value is found in the fact that Jesus Christ loved us, and gave Himself up for us.  This frees us to be simple, to respond in love, and to content ourselves with His greatness.  That is freedom indeed!
