It is sometimes difficult to understand this the way people speak today. Change takes a decision. Thoughts and convictions are a lot more stable. Although we might have a response of feelings in a given situation, we rise above those feelings and use our heads. It is then that we respond with a real understanding of growth and forgiveness.
People act on what they know.
If they know only feelings, they reduce who they are as human beings to that of the animal mentality. This is not to say that the knowledge provided by our backgrounds is fully functional. We are in a constant state of growth. Our knowledge increases every day. We willfully act on that knowledge and our interest in learning more.
