“Men loved darkness rather than light, because their deeds were evil. For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved.”
Jesus in John 3:19-20 KJV
Gospel of John
Original
ἠγάπησαν οἱ ἄνθρωποι μᾶλλον τὸ σκότος ἢ τὸ φῶς· ἦν γὰρ αὐτῶν πονηρὰ τὰ ἔργα. πᾶς γὰρ ὁ φαῦλα πράσσων μισεῖ τὸ φῶς καὶ οὐκ ἔρχεται πρὸς τὸ φῶς, ἵνα μὴ ἐλεγχθῇ τὰ ἔργα αὐτοῦ.

Poetry quotes, Poems of Pleasure (1900)
Context: I find a rapture linked with each despair,
Well worth the price of anguish. I detect
More good than evil in humanity.
Love lights more fires than hate extinguishes,
And men grow better as the world grows old.
