Law of love
43 “You have heard that it was said, You must love your neighbor and hate your enemy. 44 But I say to you, love your enemies and pray for those who harass you 45 so that you will be acting as children of your Father who is in heaven. He makes the sun rise on both the evil and the good and sends rain on both the righteous and the unrighteous. 46 If you love only those who love you, what reward do you have? Don’t even the tax collectors do the same? 47 And if you greet only your brothers and sisters, what more are you doing? Don’t even the Gentiles do the same? 48 Therefore, just as your heavenly Father is complete in showing love to everyone, so also you must be complete.
