1 John 1:6-7

1:6 If we say we have fellowship with him and yet keep on walking ¹  in the darkness, we are lying and not practicing ²  the truth. 1:7 But if we walk in the light as he himself is in the light, we have fellowship with one another and the blood of Jesus his Son cleanses ³  us from all sin. ⁴ 

[1:6]  ¹ tn The context of this statement in 1:6 indicates clearly that the progressive (continuative or durative) aspect of the present tense must be in view here.

[1:6]  ² tn Or “living according to…”

[1:7]  ³ tn Or “purifies.”

[1:7]  ⁴ tn BDAG 50 s.v. ἁμαρτία 1 defines this term as “a departure fr. either human or divine standards of uprightness” (see 1 John 5:17 where ἁμαρτία [Jamartia] and ἀδικία [adikia] are related). This word occurs 17 times in 1 John, of which 11 are singular and 6 are plural.
