His comments focusing on Proverbs as an example of a father's instruction to his child/children is more food for thought.
From my perspective, a father taking responsibility for the instruction of his children gives him opportunity to impart to his children that which has been imparted to him - more than genetic or financial heritage. It's opportunity for mentoring and impartation. A whole book in the scriptures is devoted to this. That's profound.
Does it ever amaze you, as it does me, how we inevitably miss the obvious?
