What is the ground we walk on? Whether it be cement, dirt, or grass, is there not a possibility that it collapse at any moment? What about the cars we drive in? Could we not we crash or be crashed into at any moment?
That idea, no matter how small the chance may be, should scare you. It scares me.
So why do we take it for granted? Do we grow numb to constant danger? What makes us say, "that could never be me," to ourselves?
Think about it.
A man once walked down the street, and as he walked he did many great works. Saying to himself, 'I am a truly good man,' he lived thus and was loved by many people. One day, however, as he was going on his way, a carpenter dropped a hammer from the roof of a building, which in turn landed on his head, killing him.
Was he ready to die?
