Talk to the Heart
An analysis of those words points toward a far deeper and better communication of ideas and thoughts when our words are more than simply academic. "In his language" implies touching something that is dear to the other, close to his heart, important to him. That is a far cry from a conversation that does not lead to the fulfillment of needs.
God wrote the Ten Commandments on tablets of stone. They were good for everyone in that they were there for all to see, but the people did not come to love His laws and recognize the goodness that was intended. God has introduced a second plan in which He will write those Commandments on the heart and put them in our minds (Jeremiah 31:33). God knows the value of talking to the heart of man.
