“You have heard the law that says, ‘Love your neighbor’ and hate your enemy. But I say, love your enemies! Pray for those who persecute you! In that way, you will be acting as true children of your Father in heaven. For he gives his sunlight to both the evil and the good, and he sends rain on the just and the unjust alike. If you love only those who love you, what reward is there for that? Even corrupt tax collectors do that much. If you are kind only to your friends, how are you different from anyone else? Even pagans do that. Matthew 5:43-47
This is not easy advice, but it show us what the Lord expects of our relationships with people who are not like us. Like the rain that falls on the just and the unjust, so rainbows appear to all of us.
