Sanctification is the outcome and inseparable consequence of regeneration. He who is born again and made a new creature receives a new nature and a new principle and always lives a new life.

As for the fact that Malfoy, Crabbe, and Goyle appeared to be going their different ways when they were usually inseparable, these things happened as people got older – Ron and Hermione, Harry reflected sadly, were living proof.

Our ancient experience confirms at every point that everything is linked together, everything is inseparable.
