First he practices keeping his ears open and his mouth shut. That's scriptural. In His quiet times before the Lord, I imagine he is still to listen first. He ruminates.
Think----Meditate. Concentrate."Chew the cud."
He also practices that with people.
The result is saying the most with the fewest words.
Concise. Succinct. Terse---but without the sting.
Pithy with a punch as I so often say!
Even in his work conferences he knows how to be brief because he has prepped and prayed. He uses kind, bright words to explain and encourage.
He doesn't just babble and blather on and on.
He physically leaves but his words stick.
Pithy with a punch of truth are left for others to consider.
