John 12:36

12:36 While you have the light, believe in the light, so that you may become sons of light.” 1  When Jesus had said these things, he went away and hid himself from them.

John 14:4

14:4 And you know the way where I am going.” 2 

John 17:16

17:16 They do not belong to the world 3  just as I do not belong to the world. 4 

1 tn The idiom “sons of light” means essentially “people characterized by light,” that is, “people of God.”

sn The expression sons of light refers to men and women to whom the truth of God has been revealed and who are therefore living according to that truth, thus, “people of God.”

2 tc Most mss (Ì66* A C3 D Θ Ψ Ë1,13 Ï lat sy sa) read “You know where I am going, and you know the way” (καὶ ὅπου [ἐγὼ] ὑπάγω οἴδατε καὶ τὴν ὁδόν οἴδατε, kai {opou egw Jupagw oidate kai thn Jodon oidate). The difference between this reading and the wording in NA27 (supported by Ì66c א B C* L Q W 33 579 pc) is the addition of καί before τὴν ὁδόν and οἴδατε after. Either assertion on the part of Jesus would be understandable: “you know the way where I am going” or “you know where I am going and you know the way,” although the shorter reading is a bit more awkward syntactically. In light of this, and in light of the expansion already at hand in v. 5, the longer reading appears to be a motivated reading. The shorter reading is thus preferred because of its superior external and internal evidence.

sn Where I am going. Jesus had spoken of his destination previously to the disciples, most recently in John 13:33. Where he was going was back to the Father, and they could not follow him there, but later he would return for them and they could join him then. The way he was going was via the cross. This he had also mentioned previously (e.g., 12:32) although his disciples did not understand at the time (cf. 12:33). As Jesus would explain in v. 6, although for him the way back to the Father was via the cross, for his disciples the “way” to where he was going was Jesus himself.

3 tn Grk “they are not of the world.” This is a repetition of the second half of v. 14. The only difference is in word order: Verse 14 has οὐκ εἰσὶν ἐκ τοῦ κόσμου (ouk eisin ek tou kosmou), while here the prepositional phrase is stated first: ἐκ τοῦ κόσμου οὐκ εἰσίν (ek tou kosmou ouk eisin). This gives additional emphasis to the idea of the prepositional phrase, i.e., origin, source, or affiliation.

4 tn Grk “just as I am not of the world.”
