“Samuel Zwemer, a missionary to Muslims of about a century ago said, ‘so many young people’s minds and hearts are occupied by the weak things, by inconsequential things. Their eyes have never been illumined by a great vision, their mind has never been gripped by unselfish thoughts, their hearts have never been thrilled with the passion for the lost, their hands have never grown weary and strong in the lifting of a great burden.'”
