Courage enables a person to say what is on his mind. This is wonderful for someone who has deep respect for other people. He realizes that each person is created in the image of the Creator and therefore he has a basic respect for every person he encounters.
This is wonderful for someone who consistently sees the good in others, and even though he is aware of faults and limitations, he focuses on the good and the potential good. This is wonderful for someone who is on a high level of love for other people and therefore would never want to needlessly cause anyone pain.
For courage to be valuable, the owner of that attribute needs to be sensitive to the feelings of others. While he has the assertiveness to say whatever he feels like saying, he would not feel like saying something that is needlessly painful. He will be careful how he says whatever he says. He pays attention to the outcome of his messages. Since there are always a multitude of ways to word any message, he will choose the most sensitive approach.
