"In football, each team is led by a quarterback who calls the plays during the huddle. The agreed-upon play determines how the offense will carry out its attempt to reach the goal for a touchdown. Sometimes, however, immediately before the ball is put into motion, the quarterback suddenly changes the play because he notices how the defensive team has positioned itself. This spontaneous change of play is called an audible. In real life, shifting circumstances often call for the same kind of adaptation and openness to change. To live spiritually vibrant lives requires staying receptively alert to the 'audibles' that God calls out to us. Discernment trains us to hear God's audibles and to follow a new play."
