Good and evil both increase at compound interest. That is why the little decisions you and I make every day are of such infinite importance. The smallest good act today is the capture of a strategic point from which, a few months later, you may be able to go on to victories you never dreamed of. An apparently trivial indulgence in lust or anger today is the loss of a ridge or railway line or bridgehead from which the enemy may launch an attack otherwise impossible.
C.S. Lewis, in his work "Mere Christianity," emphasizes that both good and evil grow exponentially, highlighting the significance of our daily choices. He suggests that small acts of kindness or goodness, although they may seem minor, can lead to significant positive outcomes in the future. These small victories serve as a foundation for greater achievements and can lead to personal growth and moral successes over time.
Conversely, Lewis warns that even seemingly insignificant wrongdoings can set the stage for more serious moral failings. A minor act of anger or indulgence can weaken our moral defenses and may result in greater trials ahead. The analogy of losing strategic points in a battle illustrates how little decisions can have far-reaching implications for our lives, urging us to be mindful of the weight our everyday actions carry.
