“This is Martin, 8. He died in the Boston bombing yesterday. He was at the finish line with his family, waiting for his dad to cross. His mother and little sister were catastrophically injured. He was the student of our dear friend, Rachel Moo. His message resonates powerfully today. My prayer is that we all live by Martin’s words, paying tribute to his too-brief, but immeasurably valuable life by following his example.”
