As humans, our loves, desires, and passions are unmanageably large. It has been noted, at least back to the Greek philosopher Epicurus (341-270 BC), a disciple of the presocratic philosopher Democritus, that pleasure seems to be affected by a law of diminishing returns. A particular experience brings pleasure, but the next time we have the same experience, we find less pleasure in it, and the next time even less. The pleasure of an experience shrinks and shrivels the more often we have that particular experience.
Epicurus' conclusion was to reject pleasurable experiences and find pleasure in the rejection of pleasure. Others before him and since have instead tried to experience as much pleasure as they can, seeing the dissatisfaction as something to be overcome with energetic embrace of newer, faster, and bigger pleasures. But I do not believe in the law of diminishing returns. In fact, I believe it should be rejected out of hand. Heat the tar and rip open the down pillows. Hey 'Law of diminishing returns.' Your mother was a fallacy. Meet me at the flagpole after school.
It is not the pleasure that changes. It is we ourselves that are changed by the pleasure. Our desires and our capacity for pleasure stretches and grows each time we enjoy ourselves. When our desire is fulfilled, it is the desire that grows. A pleasure that once filled a desire to overflowing seems thin, not because the pleasure has shrunk, but because the desire and the capacity for pleasure has grown. The more we find our desires fulfilled, the bigger our desires get. The more we find pleasure, the greater our capacity for pleasure becomes. Experiencing pleasure makes us want pleasure even more. If pleasure is limited, then experiencing pleasure is a dangerous game.
If there is no eternity, and if there is no infinite God, then humanity is a terrible joke. There could be nothing but dissatisfaction. Every satisfaction that we find in the world will only grow our capacity for satisfaction, and the world is not growing in its ability to satisfy. Even if we are satisfied by the world at this moment, there is nothing but dissatisfaction in our future.
If, however, there is eternal life with an infinite God, at whose right hand there are pleasures forevermore, who can satisfy us with the fatness of his house, then being human is not some cosmic prank. Satisfaction is a possibility. There is a well deep enough to quench the infinitely expanding capacity for pleasure. And that satisfaction is at the right hand of God, seated on the great white throne. That satisfaction is in Jesus.
Eternal life is spent with the incarnate, infinite, and eternal God-man Jesus, provides satisfaction. Because an infinitely beautiful and good God, who created and redeemed us, is always beyond our ever growing potential for satisfaction. Our capacity for pleasure will continue to grow, but it will never outgrow the infinite God.
