What Did Jesus Say About Loving Our Enemies?

You have heard that it has been said you shall love your neighbour and hate your enemy.

But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them who shall despitefully use you, and persecute you; That you may be the children of your Father which is in heaven: for He makes the sun to rise on the evil and on the good, and sends rain on the just and on the unjust.

For if you love them which love you, what reward have you? Do not even the publicans the same? And if you salute your brethren only, what do you do more than others? Do not even the publicans so? Be you, therefore, perfect, even as your Father who is in heaven is perfect. Matthew 5 vs 43-48.
