High self-esteem will not help you

...a high-self-esteem-will-help-you-low-self-esteem-will-hurt-you formula is not biblical. Nor is it proven in the research. It is unfortunate that many Christian leaders and psychologists have chosen to promote self-esteem. Self-fulfillment, self-actualization, self-love, and the other combinations and permutations of self-enlarging words are just various facets of the desire to be like God which originated in the Garden of Eden. Amalgamating Scripture with psychology only baptizes the flesh with the Holy Water of the Word, but it is a false message.
