Let your adorning be the hidden person of the heart with the imperishable beauty of a gentle and quiet spirit, which in God’s sight is very precious. (1 Peter 3:4 ESV)
Have you ever known someone you could hear coming before you saw them?
I don’t mean their high price shoes click clanking across the floor. I mean their loud, harsh, abrasive mouth. Talking, shouting,Gossiping, demanding etc.
I think that’s what this verse is referring to. Don’t be that person that is always giving an opinion, ranting about your personal preferences etc.
Often it is best to be silent and listen. Listen more talk less.
When you are always talking you only hear what you already know.
For growth you need to also hear what you don’t know.
