God let’s people go their own way. And whenever we can, we should let people go their own way too. Nearly all our problems come from trying to change the way others behave.*
“To try too hard to make people good is one way to make them worse. The only way to make them good is to be good.” ~ George MacDonald
Some people even justify doing evil to bring about their version of cosmic justice. In this sense, the nazis, communists and terrorists all have something in common; they all believe that they are doing what they have to do to make this world a better place. (At least a better place for “good people”—for people like them.) As soon as you say, “The end justifies the means,” you have to give up virtue in the name of a “greater cause.”
“Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience." -C.S. Lewis
“Let wisdom reign, and each man go his way.”
*Love sets the limits. It is love which causes a parent to stop their small child running onto a busy street. The greater the love, the greater the wisdom. “Love is the opener as well as closer of eyes.” George MacDonald
One of the wisest men to ever live was George MacDonald. If you are a genuine seeker of wisdom, Sir Gibbie and its sequel Donal Grant are must reads. (David Jack’s translation are the best.)
