So if someone has a thought that is wrong, they can never reconsider and correct the thought. Is there no redemption? Obama once said that gay marriage is wrong [0]. I have always thought gay marriage is correct and a fundamental right. Does that mean that Obama can never be redeemed for his earlier incorrect thoughts and beliefs. Is he doomed to be judged forever based on his egregious historical beliefs? What do you think someone needs to do for redemption?
