James 3:13

Who is wise and understanding among you? let him show by his good life his works in meekness of wisdom.

The application this has for teachers was thus presented by Tasker:

Any contentiousness or arrogance, any tendency to self-assertion, any desire to glory over others, is an infallible sign that the essential qualifications are in fact lacking.[32]

There is a moral foundation in all true wisdom, there being an utter impossibility of any wicked person being, in any sense, wise. The true wisdom is found alone in those of moral and upright character.
