The stereotypical female psychological problem is that of lack of self-esteem. The stereotypical male psychological problem is that the self-esteem is based on the self.
So often I see events aimed at Christian women (for example) trying to boost their self-esteem or sense of self-worth. All that does is teaching women to sin like men instead of like women.
The cross tells us that our self-esteem should be zero. Our sense of self-worth should be zero. Our Christ-esteem can never be high enough. Our knowledge of the fact that he accepts us despite our zero self-worth (and then seeks to transform us and use us for his glory) is where our confidence should be.
Not in self-esteem.
