Matthew 5:43-48 - The Sermon On The Mount: Love For Enemies
43 "You have heard what was said [Lev. 19:18], 'You must love your neighbor and hate your enemy.' 44 But I tell you, love your enemies and pray for those who persecute you, 45 in order to be [true] children of your Father in heaven, for He makes His sun to rise on evil [as well] as on good people. He [also] sends rain on those who live right [as well] as on those who do not live right. 46 For if you love [only] those who love you, what reward will you get for that? Do not even the publicans [Note: These were people with a bad reputation for their dishonest tax collecting activities] do that much? 47 And if you greet [cordially] your brothers only, what are you doing more than other people? Do not even the [unconverted] Gentiles do that much? 48 Therefore, you must [attempt to] be complete, just as your heavenly Father is [already] complete.
