Our eyes are incapable of seeing all there is to see. There are like scales over our eyes at the present time. There is so much in God's creation to see and understand. There will be the sense of exploring. 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. Heaven will be an eternity of discovering and knowing the wonders of our God. Happiness is a sensation of our soul and joy is a positive sensation of our spirit.
