Matthew 5:44-47

44But I tell you, love your enemies and pray for those who persecute you,

45so that you may be children of your Father in heaven. For he causes his sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous.

46For if you love those who love you, what reward will you have? Don’t even the tax collectors do the same?

47And if you greet only your brothers and sisters, what are you doing out of the ordinary? Don’t even the Gentiles do the same?
