4. He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him.
5. But whoever keepeth his word, in him verily is the love of God perfected: by this we know that we are in him.
6. He that saith he abideth in him, ought himself also so to walk, even as he walked.
7. Brethren, I write no new commandment to you, but an old commandment which ye had from the beginning: The old commandment is the word which ye have heard from the beginning.
8. Again, a new commandment I write to you, which thing is true in him and in you: because the darkness is past, and the true light now shineth.
