This is the judgment, that the light has come into the world, and men loved the darkness rather than the light; for their works were evil.
Because their deeds are evil - Men who commit crime commonly choose to do it in the night, so as to escape detection. So men who are wicked prefer false doctrine and error to the truth. Thus the Pharisees cloaked their crimes under the errors of their system; and, amid their false doctrines and superstitions, they attempted to convince others that they had great zeal for God.
