"You are little hard on yourself. Just think about it."
Sometimes it's the simplest messages, as well as the ones that descend to the natural level, that are the hardest to hear.
Since 'grace builds on nature,' we should remember that nobody likes to sit a long time on a hard seat. Firm perhaps, but not hard. So if our nature is too hard, maybe grace won't want to sit there either.
How's that for opening up a can of mixed metaphors?
