This week in Be My Witnesses, Bishop Earl Boyea of Lansing focuses on a specific form of missionary activity: giving drink to the thirsty. He asks: "Is there anything simpler than providing someone with a glass of water. This is the second of the Corporal Works of Mercy" (Matthew 25:35). Hence Bishop Boyea's challenge for this week: "visit a nursing home or a shelter or the Saint Vincent de Paul center or any other charity location. And then seek to do something very simple, like providing a drink of water."
