If you shut your door to all errors truth will be shut out.
The words 'I will forgive you, but I'll never forget what you've done' never explain the real nature of forgiveness.
Love yourself, accept yourself, forgive yourself, and be good to yourself, because without you the rest of us are without a source of many wonderful things.
It's easier to make a mistake than to forgive one. Forgive others the same as you'd like to be forgiven.
Forgive yourself for not knowing what you didn't know before you learned it.
