Princeton, New Jersey — All around the world last weekend, Christians celebrated Easter. For them, this holiest of days announced that death does not have the final word and that eternal life awaits those who would just believe.

Sunday also marked the anniversary of the Rev. Martin Luther King Jr.’s death. Forty-two years ago, an assassin’s bullet took his life as he struggled to secure the promises of American democracy for the children of slaves. His sacrifice, along with countless others, helped usher in a new chapter in American life — one that prepared the way for the election of our nation’s first African-American president.
