A poor beggar, covered with sores, miserable, hungry, sits at the gate of a wealthy man. This rich man simply ignores him. That's all. He doesn't kick this homeless man, he doesn't order him beaten. As far as he is concerned, the poor man isn't even there.
Both men eventually die. Lazarus goes to Heaven. And the rich man? He ends up in the Other Place.
His only sin was the sin of omission. He isn’t in Hell because of what he did. Rather, he is condemned because of what he didn’t do. He failed, simply, to love his neighbor as he loved himself.
How do I love myself? When I am hungry, I eat. When thirsty, I get a drink. When cold, I put on something warm. When sick or injured, I go to the doctor. I love myself in very practical ways.
I updated the setting to more modern times. The Rich Man and his Barbie girlfriend ignore the miserable man at their feet. The wealthy man's dogs, sleek, well fed, well groomed, lick the homeless man's sores. They alone recognize him as "one of the pack" and offer the only help they can.
And, here is the text, from the 16th chapter of the Gospel of Luke:
