In the parable,
the judge does not grant justice to the widow because he has a change of heart.
He doesn’t rule in her favor because of the evidence
or because she is in the right.
He grants her justice because he is tired of seeing her.
She has worn him out.
She keeps bothering him.
That is the weapon you use when you have no other.
You just keep telling the truth until the powers are worn out.
You wear out your opponent with truth and love.
