[2:3] 1 tn The translation of καί (kai) at the beginning of 2:3 is important for understanding the argument, because a similar καί occurs at the beginning of 1:5. The use here is not just a simple continuative or connective use, but has more of a resumptive force, pointing back to the previous use in 1:5.
[2:3] 2 tn Grk “know him.” (1) Many take the third person pronoun αὐτον (auton) to refer to Jesus Christ, since he is mentioned in 2:1 and the pronoun αὐτός (autos) at the beginning of 2:2 clearly refers to him. But (2) it is more likely that God is the referent here, since (a) the assurance the author is discussing here is assurance that one has come to know God (all the claims of the opponents in 1:5-2:11 concern knowing and having fellowship with the God who is light); (b) when Jesus Christ is explicitly mentioned as an example to follow in 1 John 2:6, the pronoun ἐκεῖνος (ekeinos) is used to distinguish this from previous references with αὐτός; (c) the καί (kai) which begins 2:3 is parallel to the καί which begins 1:5, suggesting that the author is now returning to the discussion of God who is light, a theme introduced in 1:5. The author will now discuss how a Christian may have assurance that he or she has come to know the God who is light.
[3:4] 3 sn Everyone who practices sin. In contrast to the πᾶς ὁ (pas Jo) + participle construction in 3:3 (everyone who has, πᾶς ὁ ἔχων [pas Jo ecwn]) which referred to believers, the use of everyone who practices sin (πᾶς ὁ ποιῶν τὴν ἁμαρτίαν [pas Jo poiwn thn Jamartian]) here refers to the author’s opponents. A similar use, referring to the opponents’ denial of the Son, is found in 2:23.
[3:4] 4 sn The Greek word ἀνομία (anomia) is often translated “iniquity” or “lawlessness” and in the LXX refers particularly to transgression of the law of Moses. In Jewish thought the ideas of sin (ἁμαρτία, Jamartia) and lawlessness or iniquity (ἀνομία) were often equated because sin involved a violation of the Mosaic law and hence lawlessness. For example, Ps 51:5 LXX sets the two in parallel, and Paul in Rom 4:7 (quoting Ps 32:1) does the same. For the author, it is not violation of the Mosaic law that results in lawlessness, since he is writing to Christians. The ‘law’ for the author is the law of love, as given by Jesus in the new commandment of John 13:34-35. This is the command to love one’s brother, a major theme of 1 John and the one specific sin in the entire letter which the opponents are charged with (3:17). Since the author has already labeled the opponents “antichrists” in 2:18, it may well be that he sees in their iniquitous behavior of withdrawing from the community and refusing to love the brethren a foreshadowing of the apocalyptic iniquity of the end times (cf. 2 Thess 2:3-8). In Matt 24:11-12 Jesus foretold that false prophets would arise in the end times (cf. 1 John 4:1), that lawlessness (anomia) would increase, and that “the love of many will grow cold” (which would certainly fit the author’s portrait of the opponents here).
[3:22] 5 tn The conjunction καί (kai) which begins 3:22 is epexegetical (explanatory), relating a further implication of the “confidence” (παρρησίαν, parrhsian) which believers have before God when their heart (conscience) does not condemn them. They can ask things of God with the expectation of receiving their requests.
[3:22] 6 tn The ὅτι (Joti) is clearly causal, giving the reason why believers receive what they ask.
