This morning, my friend shows me Psalm 37 and reminds me: "Do not fret."
I think about the word. Fretting includes a threefold experience of worry, annoyance, and discontentment about something.
Another use of the verb includes the expression fret away, as in to corrode, gnaw at, or wear down.
My fretting frets away my peace. Do not fret. Since I know that God never makes a command He doesn't also give us the power to obey, I know that I can ask for that peace that passes understanding. I do not fret. I stay at peace, soothed, and content.
The holidays often give reason to fret, so I'm thankful for this simple reminder: Do not fret!
