Matthew 5:43-48

43 "You have heard that it was said, `Thou shalt love thy neighbour and hate thine enemy.'

44 But I command you all, love your enemies, and pray for your persecutors;

45 that so you may become true sons of your Father in Heaven; for He causes His sun to rise on the wicked as well as the good, and sends rain upon those who do right and those who do wrong.

46 For if you love only those who love you, what reward have you earned? Do not even the tax-gatherers do that?

47 And if you salute only your near relatives, what praise is due to you? Do not even the Gentiles do the same?

48 You however are to be complete in goodness, as your Heavenly Father is complete.
