Context: After all these years , I now think my fears that the moral order was always in imminent danger of collapse were misplaced . My children and I have spent a great deal of time doing little else than wave it in front of each other 's noses : my lectures to them on truthfulness were more than balanced by their tirades against me on unfairness . But all the while , there was one thing we most needed even from the start , and certainly will need from here on out into the New Jerusalem : the ability to take our freedom seriously and act on it , to live not in fear of mistakes but in the knowledge that no mistake can hold a candle to the love that draws us home .
