You used to walk in these ways, in the life you once lived. 
But now you must also rid yourselves of all such things as these: anger, rage, malice, slander, and filthy language from your lips.


James 1:19-21 New International Version (NIV)

Listening and Doing

19 My dear brothers and sisters, take note of this: Everyone should be quick to listen, slow to speak and slow to become angry,

21 Therefore, get rid of all moral filth and the evil that is so prevalent and humbly accept the word planted in you, which can save you.

16 For where you have envy and selfish ambition, there you find disorder and every evil practice.

and to godliness, mutual affection; and to mutual affection, love.
