1 Yohanes 1:7

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 ¹  us from all sin. ² 

1 Yohanes 2:4

2:4 The one who says “I have come to know God” ³  and yet does not keep his commandments is a liar, and the truth is not in such a person.

[1:7]  ¹ tn Or “purifies.”

[1:7]  ² 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.

[1:7]  sn From all sin. Sometimes a distinction between singular “sin” and plural “sins” has been suggested: Some would see the singular all sin of 1:7 as a reference to sinfulness before conversion and the plural sins of 1:9 as a reference to sins committed after one became a Christian. This amounts to making 1:7 refer to initial justification and 1:9 to sanctification. But the phrase all sin in 1:7 is so comprehensive that it can hardly be limited to preconversion sins, and the emphasis on “walking” in 1:7 strongly suggests that the Christian life is in view (not one’s life before conversion). In 1 John 1:8 sin appears as a condition or characteristic quality, which in 1:10 is regarded as universal. Apart from forgiveness in Christ it results in alienation from God (2:15) and spiritual death (3:14). But according to 1 John 1:7, cleansing from sin is possible by the blood (representing the sacrificial death) of Jesus.

[2:4]  ³ tn Grk “know him.” See the note on the phrase “know God” in 1 John 2:3 for explanation.
