2:7 Dear 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. 2:8 On the other hand, I am writing a new commandment to you which is true in him and in you, because the darkness is passing away and the true light is already shining. 2:9 The one who says he is in the light but still hates his fellow Christian is still in the darkness. 2:10 The one who loves his fellow Christian resides in the light, and there is no cause for stumbling in him.
