If you observe American culture you know so much behavior is driven by envy and selfish ambition.
And, it's not hard to see -- as James says -- this leads to all kinds of disorder and evil doings (Jas. 3:16).
Just catch up on the day's political news for examples!
When observing the shenanigans of others, it's tempting to get worked up by the injustice of it all.
But James advises us to show understanding by responding with gentle wisdom and good behavior (v.13).
And he tells us... stay pure, reasonable, full of mercy and good fruits, unwavering and without hypocrisy (v.17).
Put another way...
Don't let the wrongdoing of others distract you and draw you away from the good God has called you to do.
