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