I just finished reading the book Idol Eyes by Mandisa of American Idol. It's an amazing story of a beautiful girl who followed her heart, as well as God's calling and it led her to... a data entry job for a major Christian ministry. But soon the Lord led her to sing back up for the traveling worship band for Joyce Meyers. She was happy, yet struggling with weight issues and trying to understand why she let it control her.
About that time she was encouraged to audition for American Idol and is one gal people who watched the show remember. Because after Simon Cowell commented on her weight, asking if they'd get a larger stage, she forgave him publicly--instead of causing a scene like TV producers hoped for.
I just purchased her album (love her voice) and also the Michael W. Smith Christmas CD (who I've listed to since I was a teen) and surprise! Michael and Mandissa do a duet! You can listen to it here.
