"Some of the leaders in history who provide us with the most insight and inspiration might not have had formal power or authority.
They might not even be famous.
They might not have succeeded, and they might not have won.
But these leaders often make a lasting impression on us – and the biggest impact.
Perhaps this is because the conception of leadership that we find in II Samuel, with its insistence on morality as a constraint on even the most powerful rulers, still has purchase in our world today – and that the message on leadership in the Hebrew scripture has not been entirely overturned by the Machiavellian viewpoint.
At least, not yet."
