“You’re familiar with the old written law, ‘Love your friend,’ and its unwritten companion, ‘Hate your enemy.’ I’m challenging that. I’m telling you to love your enemies. Let them bring out the best in you, not the worst. When someone gives you a hard time, respond with the energies of prayer, for then you are working out of your true selves, your God-created selves. This is what God does. He gives his best—the sun to warm and the rain to nourish—to everyone, regardless: the good and bad, the nice and nasty. If all you do is love the lovable, do you expect a bonus? Anybody can do that. If you simply say hello to those who greet you, do you expect a medal? Any run-of-the-mill sinner does that.

A good example is David in the bible, King Saul wanted to kill David till King Saul died, David had opportunity to kill Him, but He didn't, why? Because He had the fear of The Most High. When a man has the fear of The Most High, They will love their enemies, see the Messiah of Mankind, Steven, The Apostles, Joseph etc.

And then we have this :
Proverbs 16:7 When a man's ways please the ADONAI, he maketh even his enemies to be at peace with him.

Finally :
Luke 6:32-38
What credit is it to you if you love only those who love you? Why, even sinners love those who love them. 33 What credit is it to you if you do good only to those who do good to you? Even sinners do that. 34 What credit is it to you if you lend only to those who you expect will pay you back? Even sinners lend to each other, expecting to be repaid in full. 35 But love your enemies, do good, and lend expecting nothing back! Your reward will be great, and you will be children of Ha‘Elyon; for he is kind to the ungrateful and the wicked. 36 Show compassion, just as your Father shows compassion.

37 “Don’t judge,
and you won’t be judged.
Don’t condemn,
and you won’t be condemned.

“Forgive,
and you will be forgiven.
38 Give,
and you will receive gifts —

the full measure, compacted, shaken together and overflowing, will be put right in your lap. For the measure with which you measure out will be used to measure back to you!”
