James talks about praising God and then spewing hatred toward our fellow humans with the same tongue. This passage helps when we are wronged. I could give a lengthy narrative about how a wrong has happened, but what good would it do? If we are wronged, we may have our reasons why will not patronize a certain business again, but we don't necessarily need to list the grievances. Yes, it could be used as a warning to others not to use that business, but not when it's done in spite. Perhaps prayerful thanksgiving is enough that a resolution has occurred.
