More contrasts between light and darkness. Light possesses its own real power, darkness only illusory power. Light is living, darkness is dead. Light overcomes darkness. The light, which is self-existent, possesses its power in and of itself.
Light grows and produces living fruit - goodness, righteousness and truth.
Darkness produces only dead, unfruitful works. Light and truth are allies, as are darkness and the lie. Even today, light overcomes darkness through the Gospel in those who are being saved. Ultimately, light will overcome darkness completely, giving the whole world light through Jesus directly. The judgment is that men choose darkness and God ultimately gives them what they seek - hell, the outer darkness, a place where he is totally inactive.
