1 John 2:3–11

³And by this we know that we have known him, if we keep his commandments.

⁴He who saith that he knoweth him and keepeth not his commandments is a liar: and the truth is not in him.

⁵But he that keepeth his word, in him in very deed the charity of God is perfected. And by this we know that we are in him.

⁶He that saith he abideth in him ought himself also to walk even as he walked.

⁷Dearly beloved, I write not a new commandment to you, but an old commandment which you had from the beginning. The old commandment is the word which you have heard.

⁸Again a new commandment I write unto you: which thing is true both in him and in you, because the darkness is passed and the true light now shineth.

⁹He that saith he is in the light and hateth his brother is in darkness even until now.

¹⁰He that loveth his brother abideth in the light: and there is no scandal in him.

¹¹But he that hateth his brother is in darkness and walketh in darkness and knoweth not whither he goeth: because the darkness hath blinded his eyes.
