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 know we 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.
