Here's an excerpt from his website:
"With nearly ten million records sold in a career that began in 1987, Steven Curtis Chapman has recorded fifteen projects with Sparrow Records, his most recent studio record titled All Things New, released September 21st, 2004. He's received five GRAMMY awards, an American Music Award, 49 Dove Awards (more than any other artist to date), has recorded 43 No. 1 radio hits as well as numerous other honors. His platinum and gold albums include: Speechless, Heaven In The Real World, Declaration, Greatest Hits, Music Of Christmas, Signs Of Life, The Great Adventure, More To This Life, For The Sake Of The Call and All About Love. "
He is a truly gifted musician and a wonderful human being. His foundation (Shaohannahs Hope) has helped over 500 people with overseas adoption.
I would say there would be few better speakers to convey the Christmas message, IMO.
