Whenever you are feeling lonely or hurt or afraid close your eyes and picture yourself in your favorite place. Now, picture the Savior sitting beside you. Can you feel his love for you? The feelings fade away as you picture your eldest brother sitting beside you don't they?
Charity is not a feeling or a thought, it is a state of being. When you have achieved this state, you can see others how the Savior sees them.
Short, simple, and powerful. Just like the rest of the gospel, that's the beauty of our religion.
