Engaging the World But Not of the World, with Mark Olson, OCDS

In John 17: 14-16, Jesus states that we do not belong to the world. Still, He prays not that we be taken from the world, but that we may have the strength to resist evil. What do the Carmelite Saints have to say about remaining in God while being in the world?         Examples are provided from Br. Lawrence of the Resurrection, General Gaston de Sonis, and St. Teresa of Avila.
