I think mankind is going through a dark hour. With recession and ill health making life miserable for many. And sadly I don't think the majority of mankind has thankfulness for their state. Most people in the 21 Century feel they owe nothing to god. Very few people pray or concern them selves with their spiritual health.
I personally try to give thanks for every blessing. From fresh running water to having a home and some peace. I try to give thanks for the food I eat and for the peace that I live with. I try and be thankful and take nothing for granted any more. And I do feel that if people started being thankful again and learnt to count the many blessing in their lives it could only help them belong and feel satisfied with the 21st Century.
