1 John 2:9

2:9 The one who says he is in the light but still hates ¹  his fellow Christian ²  is still in the darkness.

John 12:35

12:35 Jesus replied, ³  “The light is with you for a little while longer. ⁴  Walk while you have the light, so that the darkness may not overtake you. ⁵  The one who walks in the darkness does not know where he is going.

Titus 3:3

3:3 For we too were once foolish, disobedient, misled, enslaved to various passions and desires, spending our lives in evil and envy, hateful and hating one another.

[2:9]  ¹ tn Grk “the one saying he is in the light and hating his brother.” Here καί (kai) has been translated as “but” because of the contrast present in the two clauses.

[2:9]  ² tn Grk “his brother.” Here the term “brother” means “fellow believer” or “fellow Christian” (cf. BDAG 18 s.v. ἀδελφός 2.a). In the repeated uses of this form of address throughout the letter, it is important to remember that sometimes it refers (1) to genuine Christians (those who have remained faithful to the apostolic eyewitness testimony about who Jesus is, as outlined in the Prologue to the letter, 1:1-4; an example of this usage is 2:10; 3:14, 16), but often it refers (2) to the secessionist opponents whose views the author rejects (examples are found here at 2:9, as well as 2:11; 3:10; 3:15; 3:17; 4:20). Of course, to be technically accurate, in the latter case the reference is really to a “fellow member of the community”; the use of the term “fellow Christian” in the translation no more implies that such an individual is genuinely saved than the literal term “brother” which the author uses for such people. But a translation like “fellow member of the community” or “fellow member of the congregation” is extremely awkward and simply cannot be employed consistently throughout.

[12:35]  ³ tn Grk “Then Jesus said to them.”

[12:35]  ⁴ tn Grk “Yet a little while the light is with you.”

[12:35]  ⁵ sn The warning Walk while you have the light, so that the darkness may not overtake you operates on at least two different levels: (1) To the Jewish people in Jerusalem to whom Jesus spoke, the warning was a reminder that there was only a little time left for them to accept him as their Messiah. (2) To those later individuals to whom the Fourth Gospel was written, and to every person since, the words of Jesus are also a warning: There is a finite, limited time in which each individual has opportunity to respond to the Light of the world (i.e., Jesus); after that comes darkness. One’s response to the Light decisively determines one’s judgment for eternity.
