¹⁰ The one who ^[a]loves and unselfishly seeks the best for his [believing] brother lives in the Light, and in him there is no occasion for stumbling or offense [he does not hurt the cause of Christ or lead others to sin].

²⁰ If anyone says, “I love God,” and hates (works against) his [Christian] brother he is a liar; for the one who does not love his brother whom he has seen, cannot love God whom he has not seen. ²¹ And this commandment we have from Him, that the one who loves God should also [unselfishly] love his brother and seek the best for him.
