1 John 1:9-2:11American Standard Version (ASV)
9 If we confess our sins, he is faithful and righteous to forgive us our sins, and to cleanse us from all unrighteousness. 10 If we say that we have not sinned, we make him a liar, and his word is not in us.
2 My little children, these things write I unto you that ye may not sin. And if any man sin, we have an [a]Advocate with the Father, Jesus Christ the righteous: 2 and he is the propitiation for our sins; and not for ours only, but also for the whole world. 3 And hereby we know that we know him, if we keep his commandments. 4 He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him; 5 but whoso keepeth his word, in him verily hath the love of God been perfected. Hereby we know that we are in him: 6 he that saith he abideth in him ought himself also to walk even as he walked.
7 Beloved, no new commandment write I unto you, but an old commandment which ye had from the beginning: the old commandment is the word which ye heard. 8 Again, a new commandment write I unto you, which thing is true in him and in you; because the darkness is passing away, and the true light already shineth. 9 He that saith he is in the light and hateth his brother, is in the darkness even until now. 10 He that loveth his brother abideth in the light, and there is no occasion of stumbling in him. 11 But he that hateth his brother is in the darkness, and walketh in the darkness, and knoweth not whither he goeth, because the darkness hath blinded his eyes.
