From Pastor Douglas Wilson –
Godly parents do not have the luxury of wanting to “not know” about sin their sons may have drifted into. If a son is starting to run with bad companions, or he is starting to find porn on the internet, or he is falling into a pattern of lies, they have to want to know about it. And one of their regular prayers should be that God would give them any information they need to know in order to be good parents.
