That's what partnering with God in his world-changing work looks like for InterVarsity Alumni Mac Pier and Roy Tinklenberg. After becoming friends through InterVarsity at the University of South Dakota, Mac and Roy's vision for God's Kingdom was forever transformed at Urbana '79 by speakers like Elisabeth Elliot, John Stott, and Billy Graham. Inspired by what they heard, they later went on to found organizations like Movement.org and the Faith and Work Movement, mobilizing and encouraging leaders to carry out highly contextualized ministry in cities and workplaces around the world.
