What we think about who we are becomes who we are. Positive self-esteem will run out of a positive faith about our truest uniqueness.
Unfortunately, this is accurately the reverse of the way most of us believe. We have an internalized rule which says that our uniqueness is resolute by our performance. We tend to give authority to this rule and it reinforces anything the performance is, no matter if it is pleasing or not.
The age old suggestion to "believe in yourself" really mirrors the fact of the biblical proverb about uniqueness. It is essential for us to believe that we are more than our performance. It is essential for us to think that no single performance defines us. The "loser" is not someone who constantly loses in games or at business. The "loser" is someone who thinks that these failures describe him. The "champion" is not someone who never loses a game or a business deal or a companionship. It is someone who thinks that, in malice of any loss or slow down, they are actually a winner.
Our trust about our source really affects our trust about our character. If we are led to think that we were a "error", an "accidental pregnancy" or that our parents actually didn't want children, it is harder for us to extend a positive uniqueness. Children who are appreciated and loved by their parents and who know that they are a vital part of the family unit will be superior prepared to conquer the power of some negative behaviors and still preserve a positive identity and excellent self-esteem.
The same things apply to our faith about our final source. If we think that we are the result of a long sequence of evolutionary eras that all occur by chance, we start to believe that we must set up some significant identity around what we are able to complete or achieve with this chance life we have been given. On the other hand, if we decide to believe, by faith, that we were formed by a loving God who cares about us, has a reason for us and knows us individually, we are better prepared to overcome the power of some of our pessimistic behaviors a preserve a positive identity and good self-esteem.
