2:3 Now by this we know that we have come to know God: if we keep his commandments. 2:4 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. 2:5 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. 2:6 The one who says he resides in God ought himself to walk just as Jesus walked.
