Be Honorable By Treating Others With Respect
The Sages in Pirkei Avos (4:1) define the honorable person as 'someone who shows honor and respect to other people' They are teaching us that it's not how other people treat you that makes you important and honorable. Rather, it's how you treat others.
When you realize that every human being is created in the image of the Almighty, you realize that right from birth every human being is important and valuable. By being respectful to other human beings, you add to your self-respect. You recognize that when you treat others with respect, you are expressing respect to the Creator.
