Little children, let us not love with word or with tongue but in deed and truth. ¹ 

But the one who hates his fellow Christian ¹  is in the darkness, walks in the darkness, and does not know where he is going, because the darkness has blinded his eyes. ² 

There is no fear in love, but perfect love drives out fear, because fear has to do with punishment. ¹  The ²  one who fears punishment ³  has not been perfected in love.

The one who says he is in the light but still hates ¹  his fellow Christian ²  is still in the darkness.

And now, little children, remain ¹  in him, ²  so that when ³  he appears we may have confidence and not shrink away from him in shame when he comes back. ⁴ 

By this ¹  love is perfected with ²  us, so that we may have confidence in the day of judgment, because just as Jesus ³  is, so also are we in this world.

And we have come to know and to believe ¹  the love that God has in us. ²  God is love, and the one who resides ³  in love resides in God, and God resides in him.
