1 John 2:4-7

4The one who says “I have come to know God” and yet does not keep his commandments is a liar, and the truth is not in such a person.

5But whoever obeys his word, truly in this person the love of God has been perfected. By this we know that we are in him.

6The one who says he resides in God ought himself to walk just as Jesus walked.

7Dear friends, I am not writing a new commandment to you, but an old commandment which you have had from the beginning. The old commandment is the word that you have already heard.
