Martin Luther King Jr. first delivered this famous line in a sermon at the Dexter Avenue Baptist Church in Montgomery, Alabama, in 1957. It was later included in his 1963 book “Strength to Love,” in which King expounded on his philosophy of nonviolence and his belief that a powerful, loving presence binds all humans. Although he was regularly targeted by hate speech and discrimination, King adamantly insisted that only love could rid the world of its prejudice. To this day, as people protest peacefully for equality, they embody King’s ideals, promoting love in the belief that it will someday drive out hate.
