God is love,
and whoever abides in love
abides in God,
and God abides in him.
By this is love perfected with us,
so that we may have confidence
for the day of judgement,
because as he is
so also are we in this world.
There is no fear in love,
but perfect love casts out fear.
For fear has to do with punishment,
and whoever fears has not been perfected in love.
We love because he first loved us.
If anyone says, “I love God”, and hates his brother, he is a liar;
for he who does not love his brother whom he has seen
cannot love God whom he has not seen.
And this commandment we have from him:
whoever loves God must also love his brother.
– 1 John 4:16-21 (ESV)
