John 12:35

1 John 2:11
But the person who hates his brother is in the darkness [of sin] and he lives in [harmony with] that darkness, and he does not know where he is heading, because the darkness [of sin] has blinded his eyes [to his spiritual condition].
Jude 1:13
[They are like] raging ocean waves, whose shameful actions bubble up like foam. [They are like] shooting stars [whose light quickly goes out], for whom total darkness has been reserved forever.
