But very often, for those who have self loathing and self hatred, it brings them to repentance, to an acceptance that if God loves them, then perhaps they can love themselves. I have been struck at times by just how much God approves of some people -- and it has caused me to revise my thoughts of being critical of them. If God approves, who am I to be critical? For those who are self-critical, they often need to ask themselves the same question.
Just thinking of that as I read: The Cure for Self-Hatred
Also just read a very moving post: Pillars of My Faith
Both posts are worth reading.
