Self-Esteem

Have you ever wondered at those people who want to tell others that they are special, unique, and individuals in the sight of God? I've always wanted to ask these people, 'Why then does the Bible use such "non-self-esteeming" language to describe the reality of the human soul?'
I've been perplexed where we lost sight of the fact that there isn't anything as a healthy self-esteem that is positive, uplifting, and affirmative of one's nature. How much has pop-psychology infiltrated the way we are to view anthropology? The Bible is clear on what we are before we are united to Christ. The Bible uses all sorts of vibrant and offensive language to tell us what we are truly like.
These are just the late night thoughts of my mind.
