8:12 Then Jesus spoke out again, 1 “I am the light of the world. 2 The one who follows me will never 3 walk in darkness, but will have the light of life.”
4:2 Be devoted to prayer, keeping alert in it with thanksgiving.
1 tn Grk “Then again Jesus spoke to them saying.”
2 sn The theory proposed by F. J. A. Hort (The New Testament in the Original Greek, vol. 2, Introduction; Appendix, 87-88), that the backdrop of 8:12 is the lighting of the candelabra in the court of women, may offer a plausible setting to the proclamation by Jesus that he is the light of the world. The last time that Jesus spoke in the narrative (assuming 7:53-8:11 is not part of the original text, as the textual evidence suggests) is in 7:38, where he was speaking to a crowd of pilgrims in the temple area. This is where he is found in the present verse, and he may be addressing the crowd again. Jesus’ remark has to be seen in view of both the prologue (John 1:4, 5) and the end of the discourse with Nicodemus (John 3:19-21). The coming of Jesus into the world provokes judgment: A choosing up of sides becomes necessary. The one who comes to the light, that is, who follows Jesus, will not walk in the darkness. The one who refuses to come, will walk in the darkness. In this contrast, there are only two alternatives. So it is with a person’s decision about Jesus. Furthermore, this serves as in implicit indictment of Jesus’ opponents, who still walk in the darkness, because they refuse to come to him. This sets up the contrast in chap. 9 between the man born blind, who receives both physical and spiritual sight, and the Pharisees (John 9:13, 15, 16) who have physical sight but remain in spiritual darkness.
3 tn The double negative οὐ μή (ou mh) is emphatic in 1st century Hellenistic Greek.
4 sn Jesus’ statement I am the light of the world connects the present account with 8:12. Here (seen more clearly than at 8:12) it is obvious what the author sees as the significance of Jesus’ statement. “Light” is not a metaphysical definition of the person of Jesus but a description of his effect on the world, forcing everyone in the world to ‘choose up sides’ for or against him (cf. 3:19-21).
5 tn Here οὕτως (Joutws) is taken to refer to what follows, the content of the quotation, as given for this verse by BDAG 742 s.v. οὕτω/οὕτως 2.
6 tn BDAG 1004 s.v. τίθημι 3.a has “τιθέναι τινὰ εἴς τι place/appoint someone to or for (to function as) someth….Ac 13:47.” This is a double accusative construction of object (“you”) and complement (“a light”).
7 sn Paul alludes here to the language of the Servant in Isaiah, pointing to Isa 42:6; 49:6. He and Barnabas do the work of the Servant in Isaiah.
8 tn Grk “that you should be for salvation,” but more simply “to bring salvation.”
9 sn An allusion to Isa 42:6 and 49:6. The expression the ends of the earth recalls Luke 3:6 and Acts 1:8. Paul sees himself and Barnabas as carrying out the commission of Luke 24:27. (See 2 Cor 6:2, where servant imagery also appears concerning Paul’s message.)
10 tn This term is frequently used in the LXX of the service performed by priests and Levites in the tabernacle (Exod 28:35, 43; 29:30; 30:20; 35:19; 39:26; Num 1:50; 3:6, 31) and the temple (2 Chr 31:2; 35:3; Joel 1:9, 13; 2:17, and many more examples). According to BDAG 591 s.v. λειτουργέω 1.b it is used “of other expression of religious devotion.” Since the previous verse described the prophets and teachers in the church at Antioch, it is probable that the term here describes two of them (Barnabas and Saul) as they were serving in that capacity. Since they were not in Jerusalem where the temple was located, general religious service is referred to here.
11 tn Or “Appoint.”
12 tn The infinitive περιπατῆσαι (peripathsai, “to walk, to live, to live one’s life”) is best taken as an infinitive of purpose related to “praying” (προσευχόμενοι, proseucomenoi) and “asking” (αἰτούμενοι, aitoumenoi) in v. 9 and is thus translated as “that you may live.”
13 tn BDAG 129 s.v. ἀρεσκεία states that ἀρεσκείαν (areskeian) refers to a “desire to please εἰς πᾶσαν ἀ. to please (the Lord) in all respects Col 1:10.”
