A man I know has grappled his entire life with self-hatred. And like salt in the wound, he has absorbed a notion which has only served to exacerbate all the suffering. Once, he told me, "I don't feel like I'm allowed to express any pain over how bad I hurt inside, because I'm a sinner and so anything I'm suffering is my fault anyway. That makes me angry, but then I think 'I can't be mad at God because being mad at Him suggests that He did something wrong, and since He's never wrong, it's wrong for me to be angry at Him.'"
Many of us, like my friend, are walking bottles of pain and frustration sometimes, terrified that if any of it gets seen by God, He will nail us.
