If one gives an answer before he hears, it is his folly and shame. (Proverbs 18:13)
To listen is to be actively engaged with the person that is communicating; and you should be able to know what was said as well as what was not said.
We often say more in-between the sentences than the sentences itself. Listen to the in-between silence as well as the changes in the eyes of the communicator.
Scripture is enjoining you to listen carefully to all sides of the discussion before you say a word else, you are likely to make a mockery of yourself. The person may smile at what you have said but you don’t know what he is thinking about you.
Practice listening every day!
