" When a preacher opens the Bible and interprets the word of God, a mystery takes place, a miracle: the grace of God, who comes down from heaven into our midst and speaks to us, knocks on our door, asks questions, warns us, puts pressure on us, alarms us, threatens us, and makes us joyful again and free and sure. "
