3 aBy this we know that we have come to bknow Him, if we ckeep His commandments.

4 The one who says, “aI have come to bknow Him,” and does not keep His commandments, is a cliar, and dthe truth is not in him;

5 but whoever akeeps His word, in him the blove of God has truly been perfected. cBy this we know that we are in Him:

6 the one who says he aabides in Him bought himself to walk in the same manner as He walked.

7 aBeloved, I am bnot writing a new commandment to you, but an old commandment which you have had cfrom the beginning; the old commandment is the word which you have heard.

8 1On the other hand, I am writing aa new commandment to you, which is true in Him and in you, because bthe darkness is passing away and cthe true Light is already shining.

9 The one who says he is in the Light and yet ahates his bbrother is in the darkness until now.

10 aThe one who loves his brother abides in the Light and there is no cause for stumbling in him.

11 But the one who ahates his brother is in the darkness and bwalks in the darkness, and does not know where he is going because the darkness has cblinded his eyes.
