A Los Angles Metrolink train wreck that killed 11 individuals and injured several others on January 27, 2005, left an indelible impression on Firefighter Captain Rosario. Hours after the rescue began, hope for finding other survivors was diminishing. Then one passenger indicated that another man was trapped under the debris. Using the jaws of life, rescuers were able to extricate a man named John from the wreckage. That's when Rosario saw the message.

While John was pinned under a train seat and other debris from the crash, he wrote a message to his wife and children using his own blood.

John was having trouble breathing and feared he would die. "With whatever energy he could summon and a heartbreaking economy of words, he scrawled a farewell in blood on the seat. 'I 'heart' my kids. I 'heart' Leslie,' he printed. The blood ink seemed to be running out as he got to the second sentence."

Captain Rosario discovered that message, and as he later related the story for TV cameras, the firefighter choked with emotion.

"The fact that this guy in this situation had the amount of love he had for his family, and for him to realize 'I'm possibly going to die here,' how could any words explain it?"

In a similar way, God communicated his love for the world with the blood of his Son.
