What does Jeremiah 9:24 mean?

If you want to brag about something, brag that you know and understand me—that I’m the Lord who acts with kindness, justice, and integrity on earth. That’s what I care about, says the Lord. Jeremiah 9:24 - Modern Text Bible

(The only thing worth boasting about is truly knowing God and living out his values of love, fairness, and honesty.)
