Galatians 6:14
May I never boast except in the cross of our Lord Jesus Christ, through which the world has been crucified to me, and I to the world. — Paul's counter-boast ('kauchaomai') is singular: the cross itself, wherein he shares mystical death ('stauroo' — crucified): the 'kosmos' (world, with its values and systems) is crucified to Paul, and Paul to the world, a mutual death that severs the old identity.
