Obesity has become a major problem in many of the more affluent nations. The obvious causes are eating too rich foods and the lack of exercise. Normally, one is aware of his bad habits, but is too lazy to do anything about it. It's so easy and comfortable to continue eating the same junk food, watching a lot of TV, and skipping exercise or even regular walking. Time flies and soon you are middle-aged. It's now even more difficult to change yourself in any way. The risk of suffering a heart attack or stroke rises.
Spiritual unawareness (death) happens in the same way. Normally, you are aware of your sins, but you are too lazy to do anything about it. It's so easy to rationalize away or ignore it ~ you are fooled into believing that you would feel comfortable by not facing the uncomfortable. Of course, you're wrong, for unforgiven sins stick with you forever. Again, time goes by and you become an older person burdened with even more sins. The risk of losing your soul is ever great.
