John 9:39
And Jesus said, For judgment I am come into this world, that they which see not might see; and that they which see might be made blind — Jesus states the paradoxical purpose of his coming: judgment. Those who are spiritually blind ('see not') will receive sight through faith; those who claim to see (the authorities who trust in their own understanding) will be made blind. This reversal is the judgment: the world's values are overturned. The supposedly blind beggar sees and believes; the supposedly learned authorities remain blind to the truth.
