you seem to have dug yourself into a pretty deep hole here...
I was waiting for the heart warming humanist words of consolation, inspiring and uplifting thoughts, helpful insights and heartfelt words of support to carry a bereaved stranger through the next hours, days, weeks and years - fortunately prayer doesn't have to wait for anything.
As a believer in the Lord Jesus Christ I can pray to a father, common to the victims, and call on all his promises to console, help, encourage and sustain them, so I don't feel I'm in a hole, more like on a mountain.
I don't have to send flowers, write words in books or send cuddly toys; these dear souls had the faith to go on a long pilgrimage and some reached home sooner than others.
The eyes of the Lord are over the righteous and his ear is open to their prayers.
