Love Your Enemies
"You have heard that it was said, 'You shall love your neighbor and
hate your enemy.'
But I say to you, Love your enemies and pray for those who persecute
you, so that you may be sons of your Father who is in heaven. For he
makes his sun rise on the evil and on the good, and sends rain on the
just and on the unjust. For if you love those who love you, what
reward do you have? Do not even the tax collectors do the same? And if
you greet only your brothers, what more are you doing than others? Do
not even the Gentiles do the same?
You therefore must be perfect, as your heavenly Father is perfect.
Matthew 5:43-48 ESV
