4:20 If anyone says 5 “I love God” and yet 6 hates his fellow Christian, 7 he is a liar, because the one who does not love his fellow Christian 8 whom he has seen cannot love God whom he has not seen. 9
1 sn My little children. The direct address by the author to his readers at the beginning of 2:1 marks a break in the pattern of the opponents’ claims (indicated by the phrase if we say followed by a negative statement in the apodosis, the “then” clause) and the author’s counterclaims (represented by if with a positive statement in the apodosis) made so far in 1:6-10. The seriousness of this last claim (in 1:10) causes the author to interrupt himself to address the readers as his faithful children and to explain to them that while he wants them not to sin, they may be assured that if they do, they can look to Jesus Christ, as their advocate with the Father, to intercede for them. After this, the last of the author’s three counter-claims in 1:5-2:2 is found in the if clause in 2:1b.
2 tn There is some dispute over the significance of the aorist tense of ἁμάρτητε (Jamarthte): (1) F. Stagg (“Orthodoxy and Orthopraxy in the Johannine Epistles,” RevExp 67 [1970]:423-32, esp. 428) holds that the aorist is nondescriptive, saying nothing about the nature of the action itself, but only that the action has happened. This is indeed the normal aspectual value of the aorist tense in general, but there is some disagreement over whether with this particular verb there are more specific nuances of meaning. (2) M. Zerwick (Biblical Greek §251) and N. Turner (MHT 3:72) agree that the present tense of ἁμαρτάνω (Jamartanw) means “to be in a state of sin” (i.e., a sinner) while the aorist refers to specific acts of sin. Without attempting to sort out this particular dispute, it should be noted that certain verbs do have different nuances of meaning in different tenses, nuances which do not derive solely from the aspectual value of the tense per se, but from a combination of semantic factors which vary from word to word.
sn So that you may not sin. It is clear the author is not simply exhorting the readers not to be habitual or repetitive sinners, as if to imply that occasional acts of sin would be acceptable. The purpose of the author here is that the readers not sin at all, just as Jesus told the man he healed in John 5:14 “Don’t sin any more.”
3 tn The description of the Holy Spirit as “Paraclete” is unique to the Gospel of John (14:16, 26; 15:26; and 16:7). Here, in the only other use of the word in the NT, it is Jesus, not the Spirit, who is described as παράκλητος (paraklhto"). The reader should have been prepared for this interchangeability of terminology, however, by John 14:16, where Jesus told the disciples that he would ask the Father to send them ‘another’ paraclete (ἄλλος, allos, “another of the same kind”). This implies that Jesus himself had been a paraclete in his earthly ministry to the disciples. This does not answer all the questions about the meaning of the word here, though, since it is not Jesus’ role as an advocate during his earthly ministry which is in view, but his role as an advocate in heaven before the Father. The context suggests intercession in the sense of legal advocacy, as stress is placed upon the righteousness of Jesus (᾿Ιησοῦν Χριστὸν δίκαιον, Ihsoun Criston dikaion). The concept of Jesus’ intercession on behalf of believers does occur elsewhere in the NT, notably in Rom 8:34 and Heb 7:25. Something similar is taking place here, and is the best explanation of 1 John 2:1. An English translation like “advocate” or “intercessor” conveys this.
4 tn Or “Jesus Christ the righteous.”
5 tn Grk “if anyone should say…”
6 tn “Yet” is supplied to bring out the contrast.
7 tn See note on the phrase “fellow Christian” in 2:9.

9 sn In 4:20 the author again describes the opponents, who claim to love God. Their failure to show love for their fellow Christians proves their claim to know God to be false: The one who does not love his fellow Christian whom he has seen cannot love God whom he has not seen.
