In this era, one person with grievances, real or perceived, can wreck the lives of countless others.

But one person can help, comfort, and bring goodness, too, even out of tragedy.

The words of Fred Rogers, of the old TV children’s program, “Mister Rogers’ Neighborhood,” are being tweeted and retweeted thousands of times following the tragedy in Boston. You may have read them, but they bear repeating:

“When I was a boy and I would see scary things in the news, my mother would say to me, ‘Look for the helpers. You will always find people who are helping.’”

The words are from a book Fred Rogers wrote that was published a year before he died, intended to help parents guide their children through tragedy.

Indeed, the helpers in this tragedy, from emergency responders to hospital personnel to ordinary people who offered aid, far outnumber the perpetrators of this evil. It will take much good to overcome the evil that afflicted the men, women, and children killed, injured, and grieved by the incident in Boston, but the helpers are there.

Fred Rogers died in 2003. But his words outlive him, as good often does.

“The light shines in the darkness, and the darkness did not overcome it.” (John 1:5, NRSV)
