Many a good man and woman worries over the apparent well-being and success of those whom he, she, accounts wicked! They are seen to flourish as a green bay tree, or as a well-watered garden, and this seems to be unfair, unjust, and unwise on the part of the powers that govern the universe.

If good is desirable, people ought to be encouraged to it by material success--so reason these officially good wiseacres, who subconsciously wish to dictate to God how He should run His world.
How often we hear the question: "Why is it the wicked prosper so ?" or "He's such a bad man and yet everything he does prospers." Holy Writ is very clear on this subject.

The sacred writer evidently was well posted on the tendency of human nature to worry and concern itself about the affairs of others, hence his injunction: Fret not thyself because of evil doers.
In other words, it's none of your business.

And I am inclined to believe that a careful study of the Bible would reveal to every busybody who worries over the affairs of others that he himself has enough to do to attend to himself, and that his worry anyhow is a ridiculous, absurd, and senseless piece of supererogation, and rather a proof of human conceit and vanity than of true concern for the spiritual good of others..
