1 (My little children, I am writing these things to you so that you may not sin.) But if anyone does sin, we have an advocate with the Father, Jesus Christ the righteous One, 2 and he himself is the atoning sacrifice for our sins, and not only for our sins but also for the whole world. 3 Now by this we know that we have come to know God: if we keep his commandments. 4 The 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. 5 But whoever obeys his word, truly in this person the love of God has been perfected. By this we know that we are in him. 6 The one who says he resides in God ought himself to walk just as Jesus walked.
