Learning From David
In Psalm 37 there is a series of injunctions that can help you stay focused on what is really important. David begins by saying, "Do not fret because of evil men" - people who get ahead of you by dishonest and devious means. It doesn't mean, "Just don't be annoyed with these guys," but rather it means, "Don't let them make you angry," or "Don't get burned up with these people who cut corners and laugh at fair play."
First, he says, trust in the Lord and do good. David says those who do this will have the resources of the land and be fed. The goodness he speaks of is not that of an idealist but of one whose proper and good conduct stems from the kind of a person he or she is: one of integrity, not expedience.
Then David makes a strong statement with a blessing attached: "Delight yourself in the Lord, and he will give you the desires of your heart." "Commit your way to him," he then instructs. "Trust in Him, and He will bring to pass what you really desire." Then he finally goes back to the initial theme - on the person whose success really annoys you-saying, "Rest in the Lord, and wait patiently for Him; do not fret because of him who prospers in his way, because of the man who brings wicked schemes to pass."
God will have His payday, someday. His timetable is different from yours, but eventually He will mete out true justice. Take time to read Psalm 37 and realize the lesson that can make you a better person.
For when David had served God's purpose in his own generation, he fell asleep; he was buried with his fathers and his body decayed. ACTS 13:36
