I think what I would say to a young man, is that there are categories he needs to familiarize himself with from Scripture. Two would be categories revealed particularly in Proverbs – the wise and the foolish. And I would want any young man (and this has broader application for all of us, but particularly for a young man) to familiarize himself with those two categories.
Those are the only two categories that exist. There are no other categories from God’s perspective. One either identifies with the wise or the foolish. Proverbs is a wealth of wisdom given by God as a gift from God to that age group in particular — to protect them from walking with fools, from being a fool, and from experiencing the consequences of being a fool.
