What I see in myself is one important component of self-esteem. However, it is an incomplete and often faulty picture. Subjectivity can lead to misinterpretation when assessing people, including ourselves.
One of the gravest biblical warnings is against passing judgment on someone else: “For at whatever point you judge the other, you are condemning yourself” (Rom. 2:1, NIV; see also Luke 6:41, 42). Distortion seems universal, and people are subject to commit mistakes when judging others. The same happens with self. There is a great deal of error when one judges oneself in terms of ability, looks, character, power, etc. There always are going to be people smarter, better looking, and more gifted than you; at the same time, there always will be people who will look at you and feel themselves to be inferior.
