Monday, the nation again pauses to celebrate the legacy of a man who dedicated his life’s work toward uniting a divided nation into something whole through shared values of faith, tolerance and compassion. Four days later, the U.S. will inaugurate its 45th president, whose campaign and election victory has exposed a country less united than at any time since the Civil War. It is a stark contrast, but from it, lessons can be learned that may bring us closer to the ideals Dr. Martin Luther King Jr. laid out for us.
