You might direct him to 1 Corinthinians 13 (yes--the love verses)--but it really hits home after 9/11. "..if I have a faith that can move mountains, but have not love, I am nothing. If I give all I possess to the poor and surrender my body to the flames, but have not love, I am nothing."
He can choose, being a voice of love, or a voice "full of sound and fury, signifying nothing."
