The creation (and that includes man) declares the glory of the God who created it, not the worth of self. You may respect your own body and being, but only in the same sense that you respect everything else that God made. That is not self-esteem/respect. Self has caused man to come short of God’s glory and has marred God’s creation (in himself as well as around him). This is cause for repentance and sorrow and humility, not for having a high regard (esteem/respect) of self.
"For all have sinned, and come short of the glory of God."
