1 John 1:6

6 If we say that we have fellowship with Him and yet walk in the darkness, we lie and do not practice the truth;

1 John 1:8

8 If we say that we have no sin, we are deceiving ourselves and the truth is not in us.

1 John 1:10

10 If we say that we have not sinned, we make Him a liar and His word is not in us.

1 John 2:4

4 The one who says, "I have come to know Him," and does not keep His commandments, is a liar, and the truth is not in him;

1 John 2:6

6 the one who says he abides in Him ought himself to walk in the same manner as He walked.

1 John 2:9

9 The one who says he is in the Light and yet hates his brother is in the darkness until now.

1 John 4:20

20 If someone says, "I love God," and hates his brother, he is a liar; for the one who does not love his brother whom he has seen, cannot love God whom he has not seen.

1 John 5:16

16 If anyone sees his brother committing a sin not leading to death, he shall ask and God will for him give life to those who commit sin not leading to death. There is a sin leading to death; I do not say that he should make request for this.
