¹ tn Again ἐάν (ean) in 5:16 introduces (as in 5:14) a third-class condition, but this time, with the future indicative (αἰτήσει, aithsei) in the apodosis, the condition is known as “more probable future.” As BDF §371.4 points out, such a condition describes what is to be expected under certain circumstances. If a person sees his Christian brother committing a sin not to death, it is expected that he will make intercession for the sinning brother (“he should ask…”), and that life will be granted to the sinner in answer to the request. The author has already pointed out in 5:14-15 that if believers make requests of God in accordance with his will they may have confidence that they will receive the requests they have asked for, and this is a specific instance.

² tn See note on the phrase “fellow Christian” in 2:9.

³ tn Grk “a sin not to death.”

⁴ tn Grk “he” (see the note on the word “grant” later in this verse for discussion).

⁵ tn The referent of the (understood) third person subject of δώσει (dwsei) in 5:16 is difficult to determine. Once again the author’s meaning is obscure. Several possibilities have been suggested for the referent of the subject of this verb: (1) From a grammatical and syntactical standpoint, it would be easiest to understand the subject of δώσει in 5:16 as the person who makes the request, since this person is the subject of the preceding verb αἰτήσει (aithsei) and the following verb ἐρωτήσῃ (erwthsh). From a theological standpoint this is extremely difficult, however, since it would make the person who prays for the sinner the giver of life, and it is questionable whether the author (for whom God is the ultimate source of life) would say that one believer could ‘give’ life to another. In this case the meaning would be: “he [the petitioner] should ask, and he [the petitioner] will grant life to him [the sinner], namely, to those who sin not to death.” (2) Another option is to see God as the subject of δώσει in 5:16 and the Giver of life to the sinner. This is far more consistent theologically with the author’s perspective on God as the Giver of life everywhere else, but it is awkward grammatically (as explained in reference to the previous position above) because it involves a shift in subjects for the three third-person verbs in the context from the person who makes the request (αἰτήσει) to God (δώσει) and back to the person who makes the request (ἐρωτήσῃ). In this case the meaning would be: “he [the petitioner] should ask, and he [God] will grant life to him [the sinner], namely, to those who sin not to death.” (3) A third possibility is to see God as the subject of δώσει in 5:16, but the person who makes the request (rather than the sinner) as the referent of the indirect object αὐτῷ (autw) in 5:16. This is possible because the indirect object αὐτῷ is singular, while the dative substantival participle τοῖς ἁμαρτάνουσιν (toi" Jamartanousin) which follows (which clearly refers to those who sin) is plural. Thus the meaning would be: “he [the petitioner] should ask, and he [God] will grant life to him [the petitioner], with reference to [his praying for] those who sin not to death.” Although this is a difficult and awkward construction no matter what solution one takes, on the whole the second alternative seems most probable. Even if option (1) is preferred it must be acknowledged that God is ultimately the source of life, although it is given as a result of the petitioner’s intercessory prayer and the petitioner becomes, in a sense, the intermediate agent. But in the preceding context (5:11) the author has emphasized that God is the Giver of life, and in spite of the awkwardness in the change of subjects, that would seem to be the most likely meaning here, so option (2) is preferred. Option (3) is improbable because it seems clear that it should be the sinner for whom intercession is made, rather than the petitioner, who is the recipient of life. The petitioner would be assumed to possess life already or he could not be making a request which God would hear. In this case the change from the singular dative indirect object (αὐτῷ) to the plural dative substantival participle (τοῖς ἁμαρτάνουσιν) is merely a loose construction (which by this time should come as no surprise from the author).

⁶ tn Grk “a sin not to death.”

⁷ tn Grk “a sin to death.”

⁸ tn The ἵνα (Jina) introduces a purpose clause which gives the purpose of the preceding affirmation: “we know that the Son of God has come and has given us insight (so that we may) know him who is true.”

⁹ sn The pronoun This one (οὗτος, Joutos) refers to a person, but it is far from clear whether it should be understood as a reference (1) to God the Father or (2) to Jesus Christ. R. E. Brown (Epistles of John [AB], 625) comments, “I John, which began with an example of stunning grammatical obscurity in the prologue, continues to the end to offer us examples of unclear grammar.” The nearest previous antecedent is Jesus Christ, immediately preceding, but on some occasions when this has been true the pronoun still refers to God (see 1 John 2:3). The first predicate which follows This one in 5:20, the true God, is a description of God the Father used by Jesus in John 17:3, and was used in the preceding clause of the present verse to refer to God the Father (him who is true). Yet the second predicate of This one in 5:20, eternal life, appears to refer to Jesus, because although the Father possesses “life” (John 5:26, 6:57) just as Jesus does (John 1:4, 6:57, 1 John 5:11), “life” is never predicated of the Father elsewhere, while it is predicated of Jesus in John 11:25 and 14:6 (a self-predication by Jesus). If This one in 5:20 is understood as referring to Jesus, it forms an inclusion with the prologue, which introduced the reader to “the eternal life which was with the Father and was manifested to us.” Thus it appears best to understand the pronoun This one in 5:20 as a reference to Jesus Christ. The christological affirmation which results is striking, but certainly not beyond the capabilities of the author (see John 1:1 and 20:28): This One [Jesus Christ] is the true God and eternal life.
