As we all found out somewhere around the end of Junior High School and the middle of High School (or sooner if we watched any "After School Special"), Bullies are Bullies because they lack self-esteem and self-worth and compensate for this character flaw by picking on others. It is always easier to put others down to make us bigger. However, you can always tell the most confident person in the room, because they have no need to say or do anything that puts others down around them.
Lord, help me to find my confidence in You and nowhere else.
