The home of football's Dallas Cowboys is being converted into a house of prayer for this week's Billy Graham Metroplex Mission, which starts Thursday and runs through Sunday. The 83-year-old evangelist plans to preach all four nights at Texas Stadium, where he'll appear with musicians like Randy Travis, Jars of Clay, Michael W. Smith, dc Talk and Kirk Franklin. An interdenominational committee invited Graham last fall. Since then, nearly 500 churches representing 36 Dallas-Fort Worth denominations have been preparing for his arrival. Last week, hundreds of volunteers with the Billy Graham Evangelistic Association and The Potter's House prison outreach began visiting lockups to spread the message to those who can't attend.
