The experience of pure joy will keep us from boredom. Most people generally agree that there are two sides to our existence as humans. One side of our existence is characterized by the ability to feel. The positive aspects of feeling are pleasure, happiness and joy. Pleasure is a sensation we feel with our body.
Happiness is a sensation of our soul and joy is a positive sensation of our spirit.
The other side of our existence is our ability to know. We can know and understand sensations in our body. We can go a little deeper and we experience knowledge on the level of our soul. It's at the level of our spirit where we begin to live that deep satisfying life. That's one of the reasons heaven will be so wonderful.
