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.
4:20 If anyone says “I love God” and yet hates his fellow Christian, he is a liar, because the one who does not love his fellow Christian whom he has seen cannot love God whom he has not seen.
