A belief that heaven will be boring is to believe the heresy that God is boring. That’s nonsense. Our desire for joy and pleasure come directly from God. Our capacity for joy and pleasure in this world were made by the very God we accuse as boring. Randy Alcorn asks, “Are we so arrogant as to imagine that human beings came up with the idea of having fun?”
Don’t make the assumption that real fun and pleasure is the source of “having a little fun.” Sin doesn’t make life fun. It makes life empty.it doesn’t create adventure; it blunts it. It doesn’t expand life; it shrinks it. Sin always leads to boredom. That’s why you always need a little more “sin” to get the same thrill as before.
If you think you pleasure and excitement can’t exist without sin then you are thinking with a sin poisoned mind.
In heaven we will be filled with joy and eternal pleasures. “You have made known to me the path of life; you will fill me with joy in your presence, with eternal pleasures at your right hand.” Psalm 16:11 NIV
